"Steven is a fantastic player and he might have won more caps than he already has if it wasn't for injuries earlier in his career," said the Chelsea midfielder.
"But he is a very good player and playing very well at the moment. I think he is enjoying playing in a similar way to how he plays at Liverpool.
"He has been let off the leash a little bit in that right-sided position and he is playing with all the quality we know he has got in his locker."
