Neville wrote in the Mail on Sunday: "This season may be too soon but I see signs that City and Chelsea are building teams that will win trophies not just in England but in Europe as well.
"With City, that must now be obvious to anyone who sees them. The biggest compliment I could pay to them as a United fan is that watching them beat Tottenham on Wednesday night gave me a sinking feeling in my stomach. It was as though I were watching one of the title-winning United sides - only they were wearing light blue shirts.
"Given that they seem to be making additions in central defence and midfield this summer - the two areas where they might need some cover - you can see them only improving. And now that Joe Hart, Vincent Kompany and Yaya Toure are back to their best, I think they are on a different level from anyone else."
