Unfortunately and predictably his performances have steadily declined in line with the team, but I'd be reluctant to start chopping and changing left backs as I don't think that gets the best out of either of them.
Hopefully once Silva is back and/or we see an upturn in form again, he will go back to looking like a valuable asset once again.
I think the two fullbacks are on trial as to which of them is replaced next summer, and I don't think homegrown is enough of a factor to keep Clichy any more as we seem to be coping much better in that regard now.
