Monkana looks to be very quick tricky and strong. Havent watched all of it but from what I have seen Agustein seems to gave put in a good shift and won the ball back a number of times.unlike his normal manner.
It could well be something bred into them at a young age at Chelsea of being superior. My brothers mate has a son who has been at Chelsea since he was 5 and now about 16 but when in the U10s they complained that when they played CPFC U10s at Palace training ground the pitch wasnt good enough...
