Cardiff Blues head coach Danny Wilson knows his side face a tough task when they kick off Round 2 of the Challenge Cup against Harlequins.
Thursday's game at the Arms Park promises to be an exciting affair, with both teams having started the pool stages with a win last week.
Cardiff Blues had to travel back from Italy though and Wilson acknowledged it is vital his players recover well with a short turnaround.
"I have spoken to the boys and told them the most important thing is that we recover well," he told the Blues website.
"We had a three and a half hour flight after the game to get home and a couple of days to get ourselves patched up and ready to go with one main training day, a team run and then the game.
"But we go back to the Arms Park which will give this group big motivation to perform.
"We have to use the relevant time we have got to recover properly for the fixture which, after the performance we saw from Harlequins on Thursday, is going to be a really tough one.
"I thought they showed in patches of that game what they are capable of. Their driving lineout went well and they scored a few good tries.
"Harlequins are a class act from one to 15 and with their bench too; they have internationals and have signed and recruited well to build a powerful squad.
"They play a good offloading game too so they will be a big challenge for us. But these are the games that, as coaches and players, you want to be involved in."
Reflecting on the opening round win over Calvisano, Wilson added: "We got a bonus point win on day one which ultimately puts us in a good position to go into Thursday night.
"We have got to keep building our performances. Results will take care of themselves if we perform both in attack and defence to the levels we showed against Calvisano.
"We have done that in patches this season and we know we are capable of getting wins when we are perhaps seen by many as the underdog."
