Every member of the squad has a value to the club which is impacted by a range of factors, Selling Bissouma might mean we value Trossard a little higher next week, but if the club feel that they can recoup a good sum for an individual they will do so. Our challenge is to ensure that the squad quality doesn't drop significantly in the longer term, Caicedo will get more game time and develop to reduce the gap but ultimately we hope he will surpass Bissouma. Age is a huge factor in the value of a player, in 2019 we signed a Championship CB for £20m to replace our Player of the season and broke up the D&D partnership at a time where many thought we may lose one of them to a bigger side, However 3 years later that looks like a genius move.
Money doesn't buy you a readymade superstar, the Premier League is full of players who haven't adapted. We have a model to buy very talented youngsters and give game time to anyone who is good enough to be involved in the squad knowing that when our better players reach their peak and are identified by others to be poached that we have players waiting in the wings ready to play. Some positions we are ready to replace from within but others we would need a stop gap or replacement to be signed
I do wonder how much of this is dependent on a coach as good as Potter.
