Ambrose started his professional career at Kaduna United in 2006 and two years later, he was loaned to Bayelsa United for the 2008–09 season but remained with Kaduna United after helping them win promotion.[2]
Ambrose joined Scottish Premier League club Celtic on the summer 2012 transfer deadline day, signing a three-year contract.[4] After joining the club, Ambrose praised his new teammates at Celtic for helping him settle down in Glasgow quickly.[5] Ambrose also revealed he studied British football in order to join Celtic by watching both Scottish Premier League and English Premier League games on TV upon hearing about Celtic's interest in him.[6]
Ambrose made his debut on 22 September 2012 as a substitute for Celtic captain Scott Brown against Dundee in the Scottish Premier League, a 2–0 victory.[7][8] He made his full début against Raith Rovers in the Scottish League Cup, in a 4–1 victory. He scored his first goal for Celtic in a 5–0 win over St Mirren on 20 October 2012, celebrating the goal with a quadruple somersault.[9] Ambrose went on to make his Champions League debut for Celtic, where he played 90 minutes in a 3–2 win over Spartak Moscow.[10] On 4 November 2012, Ambrose headed in an own goal, in a 2–2 draw against Dundee United. After the match, Ambrose said he let himself down and felt that he could have cleared the ball away.[11] On 7 November 2012, ahead of a Champions League game against Barcelona, Ambrose made a vow to give his best ever performance for the club.[12] After a stunning performance by the Celtic players, they won 2–1 and Ambrose said that winning against Barcelona was the 'perfect way to celebrate Celtic's 125th anniversary.[13]
At the end of the Champions League group stage campaign, Celtic qualified for the knock-out stages and faced the Italian side Juventus. In the first leg, Ambrose was named in the squad ahead of the match, only 3 days after Nigeria had won the Africa Cup of Nations, Ambrose had played the full 90 minutes in the final.[14] However, Ambrose made several mistakes during the match, allowing Alessandro Matri (first goal) and Mirko Vučinić (third goal) to score with ease. He also missed the club's best chance to score late in the game.[15] His performance was criticized by teammate Kris Commons.[15] Though criticized, Ambrose was defended by Kelvin Wilson, who believed that Ambrose would bounce back from his disappointing performance.[16] Ambrose made amends in the next league game when he scored Celtic's opener in a 6–2 win over Dundee United. Ambrose's (along with Commons) performance was praised by Neil Lennon.[17] Three days later, he scored again, in a 1–1 draw against St Johnstone. Ahead of the second leg against Juventus, Ambrose said that Commons' criticism inspired him to become a better player.[18] After the match, which Juventus won 2–0 and progressed to the quarter finals, Neil Lennon stated that Ambrose was late for training and missed the team bus from the hotel and was left to catch up by taxi.[19] Lennon also stated that Ambrose needed to "sort himself out."[20]
Ambrose came under strong criticism from fans and pundits alike for frequent poor performances and errors which led to opposition goals.[21][22] On 31 August 2016, after becoming frozen out of the first-team at Celtic under new manager Brendan Rodgers, Celtic accepted a bid of £300,000 for Ambrose from Standard Liège, but the deal fell through after he opted to stay at Celtic Park.[23] In February 2017, Ambrose's proposed loan move to Blackburn Rovers fell through, after the club was unable to obtain a work permit.[24]
Hibernian
On 28 February 2017, Ambrose joined Hibernian on loan for the rest of the season.[25] Ambrose scored his first goal for Hibs on 25 March, the opening goal of a 2–1 win in the Scottish Championship against Falkirk.[26] He won the Scottish Championship player of the month award for March 2017.[27]
After his contract with Celtic expired at the end of the season, Ambrose signed a two-year contract with Hibernian.[28] Ambrose exercised a clause in his contract and left Hibernian in January 2019, despite the club offering him a new deal.[29]
Derby County
In February 2019, Ambrose went on trial with EFL Championship club Derby County.[30] Later that month he signed a short-term contract with the club.[31]
He was released by Derby County at the end of the 2018–19 season.[32]
Livingston
After several months without a club, Ambrose signed for Livingston in February 2020.[33]
In May 2021, Ambrose was one of a few players who were released by Livingston at the end of the 2020–21 season.[34]
Ambrose signed for Greenock Morton on 26 October 2022 in a deal until the end of the season.[37] Ambrose would make his debut against Inverness Caledonian Thistle, notably being named man of the match after Morton's subsequent 4–0 victory.[38] Ambrose also scored his first and only goal for Morton in a 2–1 home victory against Partick Thistle.[39]
Ambrose made a total of 14 appearances for Morton in all competitions, before it was announced that he would be leaving the club upon the expiration of his contract.
On 23 August 2024, Bury announced that Ambrose would be departing the club after their FA Vase fixture the following day. Having continued to live in Scotland, the commute to Bury no longer proved to be a viable option for Ambrose and his family.[42]
He was called up to Nigeria's 23-man squad for the 2013 Africa Cup of Nations.[47] In the Africa Cup of Nations, Ambrose played five out of six games for Nigeria, playing in the right-back position, including the final which he started. After the tournament, Ambrose was named in the 2013 African Cup of Nations Team of the Tournament.[48] Ambrose says winning the Africa Cup of Nations was his biggest achievement and one of the greatest moments of his life.[49]
He was selected for Nigeria's squad at the 2013 FIFA Confederations Cup[50] and the 2014 FIFA World Cup. Ambrose has not been selected since 2016, due to him losing his place at Celtic. He played regularly for Hibernian during the 2017–18 season, but was not recalled for the 2018 FIFA World Cup squad.[51] This decision was criticized by former Nigeria manager Samson Siasia, who felt that Ambrose's experience would have been useful.[51]
Style of play
Ambrose often played as a defensive midfielder for the Nigeria national football team and can also play as a centre back or right back, doing so in the Israeli Premier League at FC Ashdod.[52] A ball playing centre-half, Efe is known for his composure in possession.[53] He normally performs a somersault after scoring a goal.[9][26][54]
