Southampton must be aggressive and clinical to beat Watford tonight as they look to move further away from the Premier League relegation zone, manager Ralph Hasenhuttl said.
Southampton are 16th in the standings with 36 points following a 3-1 loss at Newcastle United on Saturday.
The south-coast club conceded two goals in four first-half minutes and Hasenhuettl said they could not risk a repeat of that performance against Watford as they sit five points above the drop zone with four games left.
"I think we have the quality to win there (at Watford) or to take a point, but we need a really clinical and perfect performance," Hasenhuttl said. "The message must be that a little bit of playing football is not enough for us, so we have to be aggressive again.
"We have to work harder than we did on Saturday in the first half because otherwise against Watford, a very strong team, it is again a big problem to take something."
Hasenhuttl will be without injured defender Jannik Vestergaard for the tie and he will make a late call on Yan Valery who is recovering from illness.
"It will be difficult I think for Jannik," Hasenhuttl said. "He had big pains in the training session on Friday."
