Everton have today completed the signing of midfielder Muhamed Besic from Hungarian side Ferencvaros for an undisclosed fee.

The 21-year-old Bosnia and Herzegovina international has put pen-to-paper on a five-year deal that will keep him at Goodison Park until the summer of 2019.

Everton announced on Thursday that talks with Ferencvaros were at an advanced stage and the World Cup star then travelled with the Blues to Bangkok ahead of their friendly against Leicester City.

Roberto Martinez confirmed after the game that the transfer was close to being finalised and all formalities have now been completed.

"Muhamed is a young footballer who has developed massively in the last two seasons," the Toffees boss told evertontv. "He has been playing as a centre-half and as a defensive midfielder at an incredible level.

"What he did with Bosnia and Herzegovina in the World Cup, he showed that he is a really mature footballer, that he covers the ground really well, that he is very dynamic and technically very gifted.

"He is bringing us really good strength in an important part of the side."

Renowned for his energetic, all-action style of play, Besic impressed during three outings at the World Cup, including one against eventual finalists Argentina.

That came some three-and-a-half years after his international debut against Slovakia, when he became his country's youngest ever senior player aged just 18.

Germany-born, Besic started his professional career at Hamburg before transferring to Ferencvaros in 2012.
