With Giggs, Scholes, and Neville reaching retirement age Man Utd are urgently in need of reinforcements.
Signings like Anderson and Dimitar Berbatov have not been successful, and the former is likely to leave in the summer, the latter less so.
I think that Man Utd have overachieved this season and need to bring in two or three top quality players to rejuvenate an aging squad.
I am aware that the club has a policy of not signing expensive players over the age of 26 and where a player is over the age of 26 I have indicated as much.
Much will depend on the size of the transfer budget, Ferguson claims he still has the change from the Ronaldo sale at his disposal, but not everyone is convinced.
These are five players that I think would improve the existing Man Utd side.
Gary Neville is coming to the twilight of his career and any further contribution towards the Man Utd cause is likely to come as a substitute or second choice right back.
Rafael has potential, but demonstrated against Bayern Munich that he is perhaps not ready for a full time spot in Man Utd's back four just yet.
Ferguson needs to bring in one or two world class players to replace the likes of Neville, Scholes, and Giggs and they don't come much classier than Maicon.
Inter's unwillingness to part with the Brazilian and Man Utds lack of funds makes his arrival unlikely and Phillip Lahm from Bayern Munich might be a more realistic contender.
Maicon's age may also be an issue as he is 28. He would probably come with a £24 million price tag.
Andreas Pirlo and Xavi Alonso are probably the only two top class deep lying playmakers in the world of football.
Both men like to sit slightly behind the midfield and control the game with an impressive array of passes.
Pirlo is also a set piece wizard and competent penalty taker. He was linked with a move to Chelsea preseason and Ancelotti may well be back in for him in the summer.
Pirlo could play alongside any one or more of Carrick, Hargreaves or possibly Fletcher, but Ferguson definitely needs one more world class midfielder.
Carrick has yet to convince, persistent doubts remain over Hargreaves's long term fitness, and, despite his goal against Bayern Munich, Gibson is unlikely to command a first team place for at least another season.
World class teams need world class midfielders and Pirlo would fit the bill perfectly at Old Trafford.
Probable price: £20 million.
Ferguson has already tried to sign Robben, but was outbid by big spending Chelsea at the beginning of the Abramovich era.
He could do far worse than try again.
Robben has consistently been one of the best wingers in the game with a very respectable goalscoring record.
Nani and Valencia are both growing in stature, but with Giggs coming to the end of his career there is room for one world class winger.
Franck Ribery would be perfect, but Man Utd are not amongst the clubs who will be in a financial position to compete for the Frenchman's signature this summer and Robben is a more realistic signing.
If Bayern do sell Ribery they will be highly reluctant to part with Robben too and Ferguson will have to come in with a sizeable offer to persuade the Dutchman to follow in Owen Hargreaves's footsteps.
Probable price tag: £25 million.
Modric is one who could conceivably follow in the footsteps of Carrick and Berbatov by making the move north.
When big teams come in with big money Tottenham have a tendency to sell and Modric's fine form will have attracted the attention of some of Europe's top teams.
He can play either as an advanced midfielder or as a winger and would bring a bit of creativity to Man Utd's midfield.
Probable price tag of £23 million, or possibly less if either Carrick or Berbatov were to move in the opposite direction.
A €40 million price tag has been slapped on this prolific striker's head and such a prohibitive sum (£35 million) would probably be enough to put off any potential suitors.
A bid of £25 million might well be enough to persuade Wolfsburg to sell, particularly if combined with a transfer request.
The Bosnian scored 36 goals last season and has another 25 to his name this year. He could help share the burden of goalscoring with Wayne Rooney.
His signing would require a change of formation with Ferguson currently favouring 4-3-3 with Rooney as the main striker.
Dzeko is unlikely to be signed as an understudy to Rooney, but if Ferguson switched back to a 4-4-2 the pair could form a mouth-watering partnership.
Man Utd already have Berbatov, Owen, Macheda, Welbeck, Diouf, and now Javier Hernandez, as well as Rooney, and would need to cut this group down to a maximum of three with either outgoing transfers or loans before bringing in any other strikers.
Probable cost: £30 million.
