Arsène Wenger believes that harbouring rivalries is part of English football's culture.
Rivalries don't come much bigger than Arsenal v Tottenham and the latest battle takes place at White Hart Lane on Wednesday night.
Emotions always run high when the North London rivals meet and they will be stoked even more by the presence of Sol Campbell. Lest we forget, the 35-year-old left Tottenham for Arsenal on a free transfer in the summer of 2001.
Campbell left for footballing reasons and was rewarded with a stack of winner's medals but, even nine years on, the former Spurs captain has not been forgiven for crossing the North London divide.
He can expect a hot reception at White Hart Lane on Wednesday and, although Wenger hopes Campbell is not subject to abuse, he accepts that such friction is part and parcel of the English game.
"That's the culture of England," said Wenger at his pre-match press conference.
"It was not only Sol. You had cases before, for example a goalkeeper who played for Arsenal and Tottenham. Pat Jennings played for the two teams and maybe Jennings is more Tottenham than Arsenal in memories.
"[With Campbell] I don't know, he has grown up there. The bitterness has not come from now, it has come from the fact he left them on a free for Arsenal."
