Arsenal boss Arsene Wenger has warned Tottenham about their move to a new stadium.

This month Spurs unveiled plans to build a 56,250-seater stadium at White Hart Lane which will force the club to groundshare for one season while construction takes place.

"I just think it's much more difficult today because we built our stadium at a price that you couldn't afford any more," said Wenger. "We managed to build our stadium by subsidising it with our own resources. That is much more difficult today.

"Financially, it is the only way they can reach the next level. You cannot be in a business where you turn down 15,000 or 20,000 people every week. If your competitors have more financial power than you, at some stage you have to make a decision.

"It looks like everybody makes this decision now because when you look at Liverpool, Everton, [they] want to increase their capacity. West Ham go to a bigger stadium next season so if you stay in a smaller capacity, it's even more difficult."
