Likely a load of bollocks and there's no chance we'll be letting a CB leave (other than Otamendi), given our current predicament.
But if Arsenal (or someone else) do come in with a big offer in the summer similar to what we paid him, I'd be shipping him off.
It's a difficult one as he could come good, but you just can't trust him. He may well go on to be in some incredible form over the next few months, but he's shown that doesn't mean a lot in the grand scheme of things. He's too injury prone and inconsistent and the fact he still hasn't been extended is telling given the number of Pep signings who have been extended, despite joining after him.
If Laporte can prove his fitness over the second half of the season and get back to his best, I would be tempted to sell both Otamendi and Stones, buy a world class CB to partner Laporte, extend Fernandinho for one more season and make Garcia our 4th choice CB, with Harwood-Bellis taking the role that Garcia's been playing in this current one.
