Nani claims Manchester United hold the fear factor over Chelsea heading into Sunday's potential Premier League title decider, and labelled the Old Trafford encounter more important than Barcelona.
United could complete a marvellous Double by claiming the Premier League and Champions League titles over the next three weeks, with victory over Chelsea almost certain to wrap up the domestic scene before the Red Devils head to Wembley to take on Barca for European glory.
Sir Alex Ferguson's side have already overcome Chelsea over two legs en route to the Champions League final, and Nani believes that gives his team the edge on Sunday. Defeat for United would put the title in Chelsea's hands by virtue of goal difference, but the Portugal international is adamant the pressure is all on the Blues.
"The results against them in the Champions League were very good. I think that gives us the psychological advantage," Nani said.
"We just have to concentrate on our football and winning the game. If we do that then everything will be fine. If we win this one then it is a great advantage for us. It is nearly over then. We have a great chance."
United are expected to welcome back all their first-team stars for the weekend showdown, including the hamstrung Wayne Rooney. Ferguson has rested his prized assets in recent weeks, but Nani says there is no chance that anybody is already thinking about Barcelona.
"The most important game is Chelsea not Barcelona," said Nani, before adding about the Wembley final, "It is very important to be all together. It would another fantastic story for this club if we win at Wembley."
