I think he may go this coming week (as it is last week of the window) and we will bring in pato or teixeira.
He needs to play regularly to find his best form, wont ever play regularly here unless Costa gets a bad knock keeping him out for a long period. So as a result most, if not all, sub appearances will be poor as there is no run of form to be had.
If Palace or Villa stick 7-8 down, id be tempted to take it. To be honest
