Everton manager Roberto Martinez has said that there is more to come from Muhamed Besic, according to the club's official website.
The summer signing from Ferencvaros has been a regular in the first team in recent weeks during the absence of James McCarthy, putting in a string of impressive performances and winning over the Goodison Park faithful.
However, his manager insists that despite his good performances, there is more to come from the Bosnian and he is still finding his feet in English football.
"Muhamed is still a player that is shaping up his qualities," said Martinez.
"Something he will never be short of is technical ability, ball control and his passing range. They are aspects that are fitting in well with where he is developing in our team. He is still very young in terms of the position he is playing so I am very much looking forward to his full development and seeing how quickly he can get to the best possible level."
His international side exited at the first hurdle having finished behind Argentina and Nigeria in Group F of the tournament, but Besic's performances for his team, especially one against Lionel Messi, helped him stand out and attract Everton's interest. Martinez has now revealed he is delighted to be working with a player that caught his eye from the very beginning.
"I have been impressed since the day that I first saw him," he added.
"I have been very pleased. He has quite a unique character and personality. He wants to work every day to become the best that he can, and that is quite infectious. Mo is a phenomenal asset to our team."
