Ola John arrived at Wolves on a season-long loan from Benfica in the summer of 2016.
John, younger brother of former Fulham forward Collins John, started his career at FC Twente in his homeland.
He made his big breakthrough in the 2011/12 season, proving a key influence not only in the Dutch League but also the Europa League where he provided most assists during the group stages.
It was in May, 2012, that John was signed by Benfica, and started to figure more towards the end of that first season, including in the Europa League and Portuguese Cup finals.
There was a loan spell with Hamburg during the 2013/14 campaign, before returning to Benfica for the following season.
And in that campaign he helped Benfica win the league, Super Cup and the League Cup, scoring the winner in the final of the latter against Maritimo.
John spent the 2015/16 season on loan in the Sky Bet Championship with Reading.
He made 33 appearances with the Royals, 23 of which were from the substitute’s bench, scoring four goals.
