Tottenham boss Mauricio Pochettino admits he's a big fan of Chris Wilder's Sheffield United.
Tthe Argentine admitted his opposite number's side will prove a stern test of Spurs' credentials.
"It is going to be very difficult," Pochettino said. "They work so hard, what impressed me the most is their belief and togetherness. They have the spirit like a rugby team that fight for each other. That is fantastic to see in a football team.
"That is why they have done so well, they have a good squad, good organisation, a great manager and coaching staff. They fight for each other, they have good players, that is the key of Sheffield United, they are doing so well, they have lots of points and are in a good position in the table."
