Arsenal boss Arsene Wenger says he has great respect for managers in the lower leagues.
Wenger was relieved to see off Sutton United in the FA Cup last night.
Arsenal will face another non-league team - Lincoln City - in the quarter finals but the Frenchman has stressed he would not be willing to ply his trade in the fifth tier, despite being impressed with Sutton's quality.
"They are basically in division five and they are 17th out of 24. I will never go down there [to manage] because it is too difficult," Wenger insisted.
"[I was surprised] by the speed of their game. We had to keep our focus, I must give credit to the players who were professional and kept their focus.
"If we had come here in a relaxed mood we would have gone out because they produced quality."
