Manchester United and Liverpool have suffered a huge blow in their quest to sign Wolfsburg star Ricardo Rodriguez after the club's sporting director Klaus Allofs expressed his opinion in favour of retaining the left-back.

The Red Devils were reportedly ready to launch a genuine offer for the 21-year-old, who is also on the radar of their arch-rivals Liverpool. The Merseyside club are entering the market for a left-back and are believed to have earmarked Rodriguez as an alternative target to Sevilla's Alberto Moreno.

Louis van Gaal's side have spent £30m in signing Luke Shaw from Southampton and are seeking another player following Patrice Evra's switch to Juventus.

Earlier this year, Allofs was hopeful that Rodriguez would commit his future to the Bundesliga club by penning a long-term extension.

Following reports of the Swiss international's potential departure from the Volkswagen Arena, Allofs ruled out their prized asset leaving the club this summer.

"That will have been a brief conversation. Ricardo is not going anywhere," Allofs told Kicker.

Chelsea too were thought to be among the interested parties after they refused to give Ashley Cole a new contract. But the Blues have signed Filipe Luis from Atletico Madrid for a reported £15.8m fee.

Star performer in World Cup

Rodriguez was one of the star performers in the World Cup for Switzerland as Ottmar Hitzfeld's side bowed out in the knockout stages to runners-up Argentina.

He also starred for Wolfsburg last season netting five goals and amassing nine assists in 34 Bundesliga appearances. The former FC Zurich star still has two years remaining in his current contract and is rated at £12m.

Liverpool's attempts to sign Moreno has hit a snag due to Sevilla's demands but recent reports suggest that Brendan Rodgers's side will make one final push to land the Spaniard in the ongoing transfer window.

Meanwhile, United are said to be preparing a £17m bid to sign Ajax star Daley Blind to replace Evra. Van Gaal is well aware of the 24-year-old's talents as he was one of the stellar performers in his Netherlands squad in the World Cup.

The Dutch international's agent Rob Jansen recently admitted that clubs are interested while revealing that no genuine offer has been tabled so far.

"At the moment there is nothing concrete. But the rumours of today could very well be tomorrow's reality. There are many clubs interested in Daley. We'll have to wait and see what happens when the transfer market shakes up," Jansen told Voetbal International.
