Arsenal midfielder Nasri has just 12 months to run on his contract making his future at the Emirates uncertain. During the first half of last season the Frenchman was among the top performers in the league and would prove a great addition to any side. Arsenal are obviously keen to hold on to Nasri and the player himself has not ruled out remaining in north London: "Earlier in the season I spoke with the boss and we said we would talk during the summer, which is what we are going to do," he said recently. It's understood that preliminary talks between Nasri's agents and United have taken place, and due to his contract situation, could be available for as little as £8m.
David De Gea
Following the retirement of Edwin van der Sar, Manchester United need a new goalkeeper. Ferguson has come out and said his number one choice (to to speak) is Atletico Madrid stopper De Gea. The Spaniard is only 20-years-old, which makes him something of a risk, yet his performances for Atletico over the last two seasons have been of a consistently high standard. "I feel incredibly motivated by the fact that Manchester United are thinking about me," De Gea said. "I like the fact that they are considering me as a replacement for a goalkeeper of Edwin van der Sar's calibre." The deal could be worth as much as £20m
Jose Reina / Maarten Stekelenburg
The move for De Gea looks almost certain to go through, but should it hit a snag, Ferguson will need to find a top quality replacement. The United manager insists he will not oversee a similar situation to the one that followed Peter Schmeichel's departure when United failed to find a suitable replacement. Liverpool's Jose Reina is one that has been linked, a move that would prove highly contentious. Maarten Stekelenburg of Ajax has stated a strong interest in becoming a Red Devil.
With the retirement of Paul Scholes, the ageing of Ryan Giggs and the lack of a natural leader among their other midfielders, it is in the centre of the park that United's needs are most pressing. Dutch superstar Sneijder appears the perfect fit for United and has been strongly linked with a move to Old Trafford. Although reports are conflicting, with some suggesting he would prefer a move to Chelsea in London, and others that say he is content at Inter Milan. The 27-year-old's wages could be a stumbling block, with reports that he is currently on £170,000-a-week in Italy.
The alternative to Sneijder is Modric of Tottenham. United are desperate to secure a recognised playmaker and will go all out to secure one of these two. Spurs are hugely reluctant to sell, having turned down a bid of £22m from Chelsea, described by manager Harry Redknapp as "ridiculous". The Croatian midfielder, who was voted Tottenham's player of the year last term, has stated a desire to be playing Champions League football next year - something he won't be doing if he stays at White Hart Lane. With huge interest in the 25-year-old, it's thought Spurs will hold out for £50m, which would likely prohibit a move to United.
Real Madrid enforcer Diarra has been linked in some quarters with a move to Old Trafford this summer. It's understood that El Galacticos are willing to sell him for a fee in the region of £18m. The former Portsmouth midfielder is also attracting interest from Tottenham according to reports.
Sanchez is one of this summer's hottest players, attracting interest from all the usual contenders. Reports suggest the Red Devils have made a bid for the Udinese winger, along with Barcelona and Manchester City. It is their Spanish adverseries who appear to be leading the chase for Sanchez, with a move "80 per cent done" according to Sanchez's agent. The 22-year-old, who can also play as a support striker, scored 12 goals to help propel Udinese to Champions League qualification last season.
Rather surprisingly, United have been linked with very few strikers this summer. Current starters Wayne Rooney and Javier Hernandez fit the United mould, but Michael Owen (who's signed a new contract) is past his best and Dimitar Berbatov is far from a Fergie favourite. Perhaps a big deal will come out of nowhere, and an educated bet could be on Eto'o. The Inter Milan striker was recently quoted: "I have already shown that I have what it takes to play in Italy and I now have the idea of proving myself in England." United have been linked with the Cameroon international in the past and the 30-year-old has a fantastic track record at the top level.
Following their defeat in the Champions League final, Manchester United have been one of the most active teams in the current transfer window.
Defender Phil Jones has been acquired in a big money deal and Alex Ferguson has been noisily pursuing various other targets as United look to raise the bar.
