The first five you named, plus Neco, wouldn’t put a dint in it. Sell them all, with our best wishes, promote from within, acquire a free here and there, or a low cost signing, to cover it.
It gets tasty when we get to Gomez. I wouldn’t sell him, but if he wants to go, and the money is acceptable, we could replace him with a good young cb, with a view to being the long term partner for Konate, I’m sure.
Now we are looking at Thiago, Keita, Ox. All good players. All with durability issues. I would sell any of them, and it would boil down to money on the table. The money would be recycled into bringing the age of the midfield down, with added durability.
Up front, Mo, Bobby, Mane. This is very tricky. It would still probably boil down to money on the table for me. Obviously Mo is most important, then probably Mane, then Bobby. But if we had a real offer of say £120M for Mo, in comparison to £30M for Bobby, I’d rather sell Mo at that point, assuming we had two very good players lined up to bolster the attacking ranks.
Bottom line, some of those players are a lot more expendable than others, so no problem if and when they go. Others we definitely want to keep, but it would boil down to money on the table, and for which player/s?
