Thomas Tuchel admits he and his players must adopt a "different attitude and mindset" after falling 12 points behind leaders Manchester City at the top of the Premier League.
Tuchel gave his players time off this week before facing Tottenham on Sunday.
"We decided we would give the players two days off after Brighton to de-connect a little bit," Tuchel said.
"But the two days alone doesn't solve everything. It was good to have, and after this Tottenham game we will have another chance to give the majority of the players another two days off, because we simply need it.
