Dai Young believes Wasps face one if the toughest assignments in European club rugby when they travel to Aviva Premiership champions Saracens.
The Coventry-based club are hoping to stay in the hunt for a place in the play-offs, but Young knows Sunday's visit to Allianz Park will require an outstanding performance if the gap on the top four is to be narrowed.
"We just got over the line last weekend against Newcastle and know we'll need to up our game against the league leaders," the Wasps director of rugby said.
"Saracens are the form team not only in England, but also in Europe, having only lost one game all season.
"They are really accurate and efficient in everything they do and excel at pressurising the opposition into making mistakes. It's essential to match their accuracy and minimise errors.
"It doesn't come any harder than playing at the home of the Premiership champions, but we know on our day we can compete with the very best."
Wasps have been able call on outside centre Elliot Daly after the England hopeful again missed out on a spot in the Test side for Sunday's RBS 6 Nations clash with Italy.
Daly was released earlier in the week by Eddie Jones and is fast-tracked straight into the starting XV, joining Christian Wade and Piutau brothers Charles and Siale in the back line.
Saracens are bolstered by returning club captain Alistair Hargreaves, who starts a match for the first time in three months.
