For me I understand what Matic is actually insinuating...Don't you think Remy can out-perform Costa if given same opportunity.
Hear What Matic said:
"Remy did a good job. He scored a goal and did exactly what the coach wanted from him," Matic told Chelsea TV.
"He gives us more confidence now for the next game. I'm very excited for the next game, how he's going to play.
"Now people will see he's a very good player and he's going to be very important for us."
