Michael Carrick is refusing to get carried away over Manchester United's 1-0 UEFA Champions League win over Chelsea.
The Red Devils emerged from Stamford Bridge with a one-goal advantage and many believe that United are primed to tackle Schalke in the semi-finals.
However, Carrick is not writing off Chelsea's hopes of exacting revenge in Manchester and believes Sir Alex Ferguson's troops will be guarding against complacency.
Carrick and co have no plans to put their feet up in the return leg and he believes his team-mates will be on their game once again for next Tuesday's encounter.
"We wouldn't be saying the tie was over, no matter where we had got this result," said Carrick.
"Maybe other people would and we are confident, but we are not getting carried away.
"We respect Chelsea. It was only last season that they beat us at Old Trafford in the league and a repeat of that result would knock us out.
"We are in the position we set out to be in but it only counts for so much. Come Tuesday we need to perform again."
United will be boosted by the availability of Wayne Rooney from his two-game domestic suspension for the Old Trafford clash.
Rooney scored the only goal of the game at Stamford Bridge and Carrick believes the striker will relish the big occasion.
"When the big games come around, Wayne tends to come to the fore," said the midfielder.
"He has started scoring important goals for us again. His three at the weekend were vital and the same was true at Chelsea. It is what he loves."
