Sheffield United boss Chris Wilder knows they face a huge test against Arsenal on Monday.
Wilder was speaking at his pre-match press conference this morning ahead of Monday night's game.
He said: “If you look through their team, they don't get to where they are by being bang average.
“Even players like David Luiz and the captain of Switzerland [Granit Xhaka]. The Premier League player of the month [Pierre-Emerick Aubameyang]… Lacazette looks like being fit and available, and they spent £60m on a winger in the summer [Pepe].
"It's elite football and they've also got some players not even getting in the squad who are quite tasty, too!"
