Arsenal boss Arsene Wenger on Friday admitted he felt sorry for Andre Villas-Boas when he was sacked as manager of north London rivals Tottenham.
Tottenham used the Gareth Bale transfer cash to fund £107 million ($175m) of new talent. However, trying to get all those new men to integrate proved in part Villas-Boas's downfall in the wake of the embarrassing 5-0 defeat at home to Liverpool on Sunday.
"You need time, yes," Wenger said. "Look, when I said to you at the beginning of the season that when you sign more than three players you take a technical risk, you were all laughing at me, but it is a reality.
"If you look purely at the mathematical problem, yes it is a surprise, because he has the highest percentage rate of wins historically at the club.
"Is it an internal problem with the relationship with his chairman or with the board? I don't know. Is it an emotional reaction to a big defeat at home? I hope not because that would not be a good sign.
"I sympathise with everyone because you need to be a manager to know how much you suffer, you know how many sleepless nights are behind every manager and how much everybody wants to win.
"Of course you feel sympathy for people who lose their job."
