3. Victor Valdes
Liverpool have been keen admirers of the former Barcelona star in the past but the Spanish keeper is struggling to recover from knee ligament injury.
Monaco tried to sign the three time Champions League winner in the summer but he failed his medical and the deal fell through.
Valdes had been training with Manchester United over the last few months and could sign for the Red Devils.
It would be a huge risk signing Valdes with nobody knowing how he knee will deal with the rigours of the Premier League.
