There are obvious areas of need like LB, which I'd like to see us address. As for other positions, it could well be that Silva is still assessing what he's got at the club. There was lots of talk about Allardyce having the best squad of players he's ever worked with, here, well, the same goes for Silva. Maybe he had Brands support in going for Carrillo but having seen Mirallas/Bolasie/Sandro in training he's thought "with my tactics, instruction and man-management skills, I can get these players to a level, equal to anyone who would be willing to come here'. It's a massive squad and although the new regime will have had their preconceptions; that's not to say the transfer strategy has changed somewhat, having actually spent time with the players.
