Former Arsenal boss Arsene Wenger insists there's more to Manchester City's Treble than big spending.

City clinched the triple crown by winning the Champions League last night.

Wenger told beIN SPORTS: "When you talk about finances, what is clear is when you have this quality of players in the squad now. You need super money.

"Just to live from the normal income is not sufficient. The teams at the top now seem to have a stake behind them and unlimited resources - a long-term plan.

"What I like about City is that they have huge financial resources they have used it in a intelligent, rational and consistent way. They [the owners] bought Man City in 2007 and they were not impatient.

"The team that plays tonight, they slowly got rid of the players that do not meet the mentality you need to win at the top level. I don't speak about the football quality, but the mental quality.

"Year after year, they built the team to be mentally strong at the top. That's why, after the financial aspect, we know to get to the top you need huge resources - they use it in an intelligent way.

Guardiola has spent £1.2bn as City manager, but Wenger added: "I don't think about it like that.

"Guardiola is a top class coach and has survived at that level because he has the quality. Top class players without a top class coach will not do well - you need both of them."
