Nigel Clough says there is a 'buzz' around Bramall Lane for Tuesday's Capital One Cup quarter-final clash with Southampton.
Looking ahead to facing Ronald Koeman's side, Clough is acutely aware of the importance of a solid start against the Saints, who enter the game in fifth place in the Premiership.
The Blades boss acknowledges his side are underdogs, a tag his players enjoy, but Clough says United are determined to push Koeman's team all the way.
Looking ahead, Clough remarked: "The incentive again has to be the semi-finals and who knows beyond that, we know it is going to be extremely tough, but if we were to get through we would be two games away from a Wembley final.
"We have to be relaxed, we don't want to give anything away early on, let's not do anything daft, just let the game settle down.
"We will pay Southampton a certain amount of respect because of what they are capable of, but it is important we don't show them too much.
"We know they are towards to the top of the Premier League for a reason, but in cup football anything can happen and our lads seem to relish the tag of being the underdogs.
"We are fully focused on Tuesday night, the supporters will be the same, we will put our strongest possible team out there and there is already a real buzz about the place, but league points remain our priority and Saturday's game with Walsall is another big one for us."
