I cant even begin to make excuses for any of those three.
If we got shut of them and brought in replacements we'd either be the same or better.
Alli - I believe should be given more time to see if he can recapture pre-Mourinho form, but an issue potentially if and when appearances trigger big payments
DCL - is perhaps overrated in that he hasn't been around long enough to perform season after season. Coming back from injury and with less service I don't believe we should be completely hanging our hat on him. It was Ancelotti who got the best out of him. Need another striker in there too to replace Richarlison
Godfrey - is quite good isn't he? Struggled with some injuries and was playing in a defence with others around him shot of confidence or advancing in years (in Coleman's case)
Others:
Davies - home grown but maybe not quite the quality level to be a first team regular in what we aspire to, OK as a squad player I guess. Could be the time for him to move to a smaller club where he's a regular starter
Doucoure and Allan - are actually pretty good aren't they?
Rondon - advancing in years, wasn't fit when we signed him, associated with Benitez. If back to full fitness could be OK though as backup striker (3rd choice), rather than paying to get someone new
