If it were a straight choice between
a) another season or two of Given and losing Hart
or
b) keeping Hart for the next ten years of his career and losing Given
I'd take b) every single time.
Hopefully that isn't the choice but neither would be happy with playing second fiddle to the other next year, and rightly so.
All this, "he should come back and compete" stuff is nonsense. It doesn't work like that for keepers and anyone thinking that a keeper as good as Hart should be happy to play a few cup games and then take a 50/50 chance of maybe becoming first choice, is expecting him to do something that no other top keeper would do.
Personally, I rate him as at least as good as Given.
Mind you, I thought that before Given was signed, after he was signed and ever since.
If it has to come down to making a choice between the two and the club choose Given, dumping Hart, I will be devastated.
Hopefully, Mancini would make the correct decision. Under the Welsh numpty Hart would have been shipped out without second thought, in that scenario, purely because he wasn't a 'Hughes man'.
Another season on loan for Hart might solve the problem but you have to guard against giving him the impression that he is going on loan because he isn't yet good enough to replace Given. And given the way Hart and Given have performed over the last two years (or over their whole careers imo), that just isn't the case (and that isn't disrespect to Given, Hart just has so much more to his game)
