I'd be nervous if I was Stones. Pep's clearly lost trust in him and Garcia's really starting to make a case for himself.
With seemingly no movement on his contract extension, constant injuries, no improvement on the field and issues off, I wouldn't be shocked to see him shifted alongside Otamendi in the summer and at this stage, I wouldn't be completely adverse to it.
Get Garcia settled as a credible option for the remainder of the season and get him signed up for the future. Tie Fernandinho down to a one year extension. Sell Stones and Otamendi to fund a world class (or young talent on the periphery, similar to Laporte) CB to come in and partner Laporte.
Laporte, new signing, Fernandinho, Garcia and Harwood-Bellis as our options.
Give the latter two young lads a season to see if they're up to scratch as 3rd/4th choice options once Dinho leaves us, if it's not quite working out, we can always make another signing for the 21/22 season, but they're both big talents and could save us some serious cash. Not to mention how fantastic it would be to have two academy lads as proper squad members.
It's felt like we've gone on for so long saying how this is Stones time to step up and it's never materialised. Unless we see a massive resurgence from him in the final half of the season, I would be tempted to cash in to help with our 'rebuild' whilst his value is still going to be relatively high.
