I think its a broader equation, Idrissa is a good player but hes far from being world class in my opinion. I think hes a one dimensional player and at his very best hes good at that dimension. Lets be honest though, we have been poor enough and have had trouble conceding goals since hes been with us, personally i think he has peaks and troughs with form, when hes on it hes great, when hes off it he can be powder puff. Lets not fool ourselves into thinking hes some world class gem we have uncovered. He was part of the team that capitulated a 2-0 nil lead to Newcastle less then a month ago in the final stages of the game, you want your midfielders to manage that game, especially senior ones. Hes a good player, not a great one and even in my life span ive seen many superior multi dimensional midfielders play for Everton.
Regardless of my opinion, there is a pragmatism that needs to be adopted. We have seen the difficulty in recruiting and keeping players in their late 20's. Our wage bill is indicative of that. What we have decided as a club is to move to a younger model of investing and developing players. We also know that regression with players who rely on stamina, athleticism and mobility regresses in their early 30's, the age Idrissa will be moving into. Yes he might provide a similar service for a couple of years, but it is a position we will have to look at in the short term anyway. So if a club offers you a 300% - 400% profit on your outlay a couple of years early and you have a more then apt replacement you have a faith in to come. There is a tipping point there where it becomes a better decision to sell then keep. If he was 22 - 24 i would think a bit differently, but then a transfer fee would be higher as well.
You are advocating loyalty and that is were i think you are being naive, you are saying things like we didnt buy him to sell him, that wildly naive. Footballers are investments and no one has loyalty in football, if hes rubbish we will want him binned, if it suits the club we will sell him in a heart beat if the deal is good enough. he himself agitated for a move in January and could be going for round 2 in the summer.
Im very open minded about it, if its the right fee and we have the right player to replace him, it could very well be a no brainer, but those would be my criteria. im pretty comfortable about it knowing we hold all the cards. Better midfielders then Idrissa have left Everton and we have progressed.
So saying there is zero% of selling him based on all of the above is just wildly naive. I think the point you are making is you really want to keep him, im sure because you like him as a player. But like i said its s broader equation.
