It's not about getting them for less, if anything id rather pay that bit extra and get a word class player rather than spunking £25m on a good/mediocre player like Mccarthy.
Let's look at some of the names supposedly (according to reports) could be open to a move this summer. Rakatic, Fabregas, Pogba, Kroos and god knows who else, we should be in for that type of player not settling on Mccarthy 2 weeks after the season as finished. The likes of Koke.
Bottom line is Mccarthy isn't worth £25m and that's what Everton would want. £52m on Fellaini and McCarthy is a joke to be honest.
