Wait there, so Kovavcic is good enough but Ross isnt?
Barkley didnt have the best of games today, but no one in a Chelsea shirt did.
Following a long lay off, he started the season tremendously when everyone more or less wrote him off. Came up with some crucial goals and assists and rightfully got his England call up, in which he bossed the game against a Spanish midfield consisting of Thiago, Saul and Busquets - all of which most on the Caf would deem world class.
Yes, he has been in poor form of late, but who in a Chelsea shirt hasn't?
He, along with every other Chelsea player, is suffering from the slow, predictable play of Sarri's system.
Will he go on to be a top class player and be pivotal to a team winning titles, who knows? I just find people are too quick to say some players are not good enough when they go through a dip in form.
