MFK Kosice have admitted it is 'likely' that Middlesbrough target Nemanja Matic will be playing in the Premier League in January.
Matic will train with Middlesbrough this week, although his trial has been cut short after he was called up to the Serbia squad for the friendly with Poland on Sunday.
The midfielder is wanted by several clubs across Europe, but would prefer a move to England, with Boro having close ties with Kosice.
The Slovakian side are keen to hang on to the 20-year-old, but head of football development Allen Bula concedes Matic is likely to move when the transfer window reopens.
"Even though we don't want to lose Matic, it is looking more likely he will be playing in the Premiership in January," Bula told skysports.com.
Matic's selection for Serbia's game with Poland is his first call-up to the senior squad and Bula has no doubts that the youngster can go on to become a top player.
He added on the club's official website: "We always knew that this player would become a star player in Europe.
"MFK Kosice's player development programme has shown once again that players, when given the right timeframe, will become star players like Nemanja.
"I am sure that Marko Milinkovic, ther other Serbian Under 21 international we have, will be called up for the senior Serbian side in the near future."
Boro have already agreed a deal to sign Peter Gal-Andrezly on loan from Kosice, while Juraj Hovancik is due to join Matic on trial on Teesside.
