The Harambee Stars man spent a loan stint with Girona FC in the 2017/18 season before moving to sign with the Japanese side
Kashiwa Reysol and Kenya's striker Michael Olunga has revealed how much of a step up in terms of pace and technique is required when playing against the best teams in the world, like Real Madrid and Barcelona.
Olunga spent the 2017/18 season in La Liga turning out for Girona FC and made just 14 appearances, scoring three goals during the loan stint.
He says facing the two giants was a big moment for him, but admitted how much more difficult it is to play against sides like that.
