I'm all for having the newly signed player come in and join the team after the summer, doing 5v5 training matches with the guys and in general just build chemistry and understanding with them from the very beginning. It's not that crucial to play matches for 5 months. Just look at Vermaelen, he was out for nearly a year and couldn't even train for most of this time, yet he came on against Deportivo and played really well after just training with the guys for a couple of months. Same with Suarez, he didn't need much time to adapt either since he had been training with the team during his ban.
So again, and this goes for all our potential signings this summer - I want them to come over and train instead of being loaned. I think this is the the most effective way to integrate them into the team and the quickest way for them to absord the way we play, plus it also gives Lucho complete control over their training regimen.
