Aston Villa goalkeeper Brad Guzan has told the club's official site of the lesson that the squad have learnt after their defeat to Swansea City at the weekend.
Villa went down 1-0 to Swansea and Guzan admits that the defeat was a reality check for his team.
The Claret and Blues had gone into the game full of confidence after beating Sunderland 4-0 in their most recent fixture and Guzan admitted that they may have got slightly carried away from that victory.
"We had a good feeling after our win at Sunderland but we know now that we can't get too high or can't get too low," he said.
"We've got a break before the Man Utd game. We'll regroup, recover and get ready to go again."
Villa's defeat to Swansea was a disappointing blow for the side as it puts them back into trouble.
The Midlands side had improved considerably since Tim Sherwood's appointment, but they are still only three points clear of the drop-zone and that is far too close to comfort.
Villa face Manchester United after the international break and they will be determined to bounce back from this defeat, but the fixture at Old Trafford is looking like a tricky one.
United have improved in their last two matches - against Tottenham Hotspur and Liverpool - and it will be a tough test for Villa to get any points from the match.
Whatever is the outcome of the match, it seems that Villa will not be getting too carried away, though, with Guzan determined to remain calm for the rest of the campaign.
