Put Balanta (CB) on your shortlist so if anyone bids then you won't miss out, but IMO I wouldn't buy a CB with Utd for the first season as Jones and Vidic is a brilliant CB pairing alone, then the 2nd season get in Balanta.
Play Fellaini BWM, focus on creativity in your team. You've also got Nick Powell who can (depending on his PA in your save) turn into a monster. For AMR play Kagawa (unless your'e playing him AML). Your budget is tiny for a club the size of Man Utd's though, so I'd just spend the whole thing on one player. Drop Rooney to AMC, Mata AMR and Kagawa AML, then spend heavily after the season on quality players.
