Tottenham, in contrast, have yet to make a single addition, but Vertonghen believes that is a positive because there is not as much expectation on them as there is facing their Premier League title rivals.
Alderweireld was one of Spurs' defensive stars last season, when they finished second in the Premier League, and last month he rejected claims he had turned down a contract offer from the club.
"I totally understand the fans showed they're disappointed with the situation", said Pochettino.
Last season's champions Chelsea and sixth-placed Manchester United have also spent over £100m, and Spurs chairman Daniel Levy and manager Mauricio Pochettino have always been clear that they can not compete with their rivals in the transfer market.
City are sure to be buoyant heading into this match, having bounced back from a defeat to Manchester United by seeing off Real Madrid 4-1 in the second of their three International Champions Cup matches. "You've seen how much money has been spent in the window and there's a month still to go, it's insane".
The Belgium worldwide said: "With their spending, then a lot of pressure comes on those teams".
'I'm happy everyone has strengthened their teams because that makes it so much better when you beat them, ' Vertonghen said. With spending, there's a lot of pressure on the teams. It's a great thing to play in it.
"Danilo and Kyle Walker help us a lot to show us our rhythm".
"But it's a football match and I want to win, so if we can go there and pick up a victory that would be fantastic". I think we have a great team, a young team. "This looks like a pre-season where we finally have everyone together, or nearly everyone, and can work on things the manager wants and I think we've seen lots of improvements already". "We've seen lots of improvements already".
