Manchester United are set to revive their interest in Gareth Bale, as Louis van Gaal has hinted that there can be a "surprise" signing before the end of the transfer window, according to the Sunday People.

The Welshman has been heavily linked with a move to Old Trafford over the past two seasons and the Red Devils are willing to spend up to £95m ($148m) for his signature should Real Madrid choose to let him leave this summer.

United are likely to make one last attempt to convince Bale to move back to the Premier League with Van Gaal looking to end his transfer business with a flurry, after signing four players already in the summer window.

Morgan Schneiderlin, Bastian Schweinsteiger, Matteo Darmian and Memphis Depay have already moved to Old Trafford, with the Red Devils still in the market for attacking and defensive options.

Van Gaal saw his side beat Club America 1-0 in their opening pre-season game with Wayne Rooney up top, but they only have James Wilson in the squad to provide some backup. The manager said that he will bring Javier Hernandez back in the squad after the striker spent a year on loan at Madrid.

However, with Radamel Falcao having moved to Chelsea and Robin van Persie to Fenerbahce, they are slightly light up front. The Guardian reports that United are also looking to trigger Barcelona winger Pedro Rodriguez's release clause, with Chelsea also interested in his signature.

Spanish publication Sport reckons that Jose Mourinho and Cesc Fabregas have both talked to the winger and convinced him to join the London club, but United are a late entrant in the race.

Meanwhile, the BBC has reported that United are at a impasse over the transfer of David de Gea, with the club stating that they would reject any bid from Real Madrid unless Sergio Ramos is involved in a move to Old Trafford.
