Chelsea midfielder Nemanja Matic says they must be wary of Newcastle United striker Aleksandar Mitrovic today.

As a fellow Serbian, he's a player Matic knows well.

"We've played together for the national team and he's an interesting player, he's young and he moved to Newcastle from Anderlecht," his compatriot told the Chelsea website.

"He's very talented but he can still improve further. He's come to a very difficult league and it will be good for him to play against such good defenders. I know it's not easy when you are young going up against such top players but I'm sure he will get better during his time at Newcastle. He's already scored a few goals but I hope on Saturday he misses the target."
