The argument for keeping DCL in the team ahead of Beto is getting weaker with each game.
I don't know what is the issue with DCL but at the moment he looks absolutely toothless, almost disinterested.
Beto, on the other hand is now playing the way we would want our striker to full, full of endeavour and commitment. He may be limited in certain areas of his game but even those will improve somewhat if he gets regular game exposure.
I have been a big fan of DCL for years but now I can't see any reason for him to stay in the team.
