Arsenal go into their first game in the Champions League tonight against Borussia Dortmund.
“It is as difficult to win the Champions League because a team that wins the Premier League is in the Champions League final almost every year.
“Outside the country, Barça and Real Madrid have much more financial power than they had 14 years ago because they have individualised their TV rights. So they, at the moment, with teams like Man City and Chelsea can take who they want.”
