Actually Chelsea got the best bosman signing in recent years - Ben Haim. Not only is he a good backup for Terry and Carvalho, his arrival also paves way for Boularhouz to say bye bye.
United obvious weakness last season was the strength in depth. Silvestre, Fletcher, O'Shea and Richardson are never gonna make it big a United and Brown only did well marginally.
The signings - Anderson, Nani and Hargreaves adds quality depth in squad. It also signals United's intention for the next season - win as many trophies as they can.
Cheers.
