Sir Alex Ferguson says Manuel Neuer's performance against Manchester United may be the finest he has come up against in his 25 years at the club.
United were dominant at Schalke in Tuesday's semi-final first leg and produced a catalogue of clear-cut chances, but they were unable to beat Neuer during the first-half.
On 50 minutes, Javier Hernandez fired the ball into the net having been ruled offside, and Ferguson believes that paved the way for Ryan Giggs and Wayne Rooney to score in the 67th and 69th minutes, but he was still left in awe of Neuer's performance.
"In my time at United, it is probably the finest display of goalkeeping against us," Ferguson said. "I am sure there have been other feats but tonight I saw a very good one.
"There was a frustration towards the end of the first-half when Neuer made another save from Ryan. When that move broke down our players started walking back and I sensed a bit of frustration. We had to correct that at half-time
"But the thing that broke the camel's back was Javier Hernandez's goal being chalked off. That took away the frustration of the players because they knew they could actually beat the guy even if it was not easy."
Ferguson is believed to have looked into the possibility of signing Neuer as a successor to Edwin van der Sar, but it seems the Germany international has already agreed a move to Bayern Munich.
Asked whether he would make any effort to sign Neuer in the wake of his performance, Ferguson said: "I think we know [he's going to Bayern]."
