Neville expects all the major clubs to spend big this summer.
He told manutd.com: "There was an incredible end to this season with all the retirements and Sir Alex in particular retiring. But in some ways it wasn't the most exciting Premier League season we've had with United winning the league with four games left. The season before was ridiculous in terms of excitement because of what happened on the last day - you'll never see anything like that ever again. But I think the quality was just a little bit below that this season, not at United but just generally throughout the league.
"The German league, as an example, is that little step above us at the moment. We will get back there though. It's going to be a big summer and a big season - we'll see players grow and top players will be added to various squads. When you look at the existing squads that the top four or five clubs have and the fact that two or three additions will come into each I think we'll be talking about them being some of the best teams in Europe again next season."
