As a two-year-old, John fled with his mother and brothers from Liberia to the Netherlands. His father was killed during the bloody First Liberian Civil War. He did not return to the African continent until the Youth World Championship in Nigeria in 2009. As a child, he played at the amateur club VV DES in Nijverdal. Like his brothers Collins and Paddy, Ola joined the youth academy of FC Twente.
The 2011–12 season was the big breakthrough for John at FC Twente, as he got a starting place from Co Adriaanse at the start of the season, and did not lose that even with competition for the left forward position, as Nacer Chadli returned from injury. He also topped the UEFA Europa League group stage assist rankings with six assists. In Twente's home match in the Europa League against Odense BK on 3 November, John provided all three assists in a 3–2 win. John was influential in the Eredivisie campaign as well, netting two goals in a 6–2 victory over FC Utrecht on 4 December 2011.
On 24 May 2012, John signed for Portuguese giants Benfica for an initial €9 million – eventually rising to €12 million due to clauses – on a five-year deal that includes a €45 million release clause. After struggling to find his space in the first team during his initial months in Lisbon, John became a regular starter or used substitute in the second half of Benfica's 2012–13 campaign, which included presences in UEFA Europa League and Portuguese Cup finals.
He was loaned to Hamburg for the remainder of the 2013–14 season on 17 January 2014. He remain in the squad for the new season, scoring his first league goal for Benfica at 12 September 2014, against Vitória Sétubal. On 5 October, he made 2 assists in a 4–0 home win against Arouca in Portuguese league.
In February 2012, John was called up for the first time by Bert van Marwijk to represent the senior Netherlands football team for the game against England at Wembley. On 7 May 2012, he was named in the provisional list of 36 players for the UEFA Euro 2012 tournament, one of nine uncapped players to be chosen by Netherlands manager Bert van Marwijk as part of the preliminary squad.
