Leeds United boss Marcelo Bielsa admits they won't be at full-strength for tonight's FA Cup tie with Arsenal.
Leeds, who are top of the Championship, are without forward Eddie Nketiah, who was on loan from Arsenal but who has now been recalled.
Bielsa says defender Robbie Gotts and goalkeeper Illan Meslier will make their debuts, with defenders Gaetano Berardi and Barry Douglas also starting.
"Of course it is a big challenge for us. It is enough to see the players and the prestige and level they have," said Argentine Bielsa.
"When people think that we are the favourite in one match, we don't consider things like that - and neither do we with the opposite, which is in this case.
"Every time we compete, we trust in our resources and respect our opponent's resources.
"We will always do this with the wish to impose our style, and we will try to do this on Monday."
