Nemanja Matic's backed Serbian countryman Aleksandar Mitrovic to bring more goals to Newcastle ahead of their meeting at Stamford Bridge.
Chelsea midfielder Matic will be up against striker Mitrovic this evening.
Mitrovic, signed from Anderlecht last summer, scored his fifth goal of the season in last weekend's 1-0 win over West Bromwich Albion at St James's Park.
"We’ve played together for the national team, and he’s an interesting player," said Matic, who has played alongside Mitrovic for Serbia.
"He’s young, and he moved to Newcastle from Anderlecht. 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."
