If you plan to have two or three loans it can because you can commit funds to transfers for two or three quality players and bring in loan players you couldn't usually get like Welbeck, Evans, Rose, Borini etc. if you end up with half a dozen then it's a challenge to replace them and gets in the way of developing your own players.PVA was a big downgrade on Alonso, imo and I'm sure many on here. Ki was massive for us in the period of the season we played our best football, December through February, he basically made us tick. Borini was massive for us.
The point is, we have to sign four players at least just to stand still. Then more on top to improve.
For example, if Mvila, Toivonen and Yedlin become key players (very possible in case of the first two), we'll be dipping into our budget to sign two or three players (either signing them permanently or replacing them) just to stand still. I really don't feel it's a sensible way to implement long term success.
