Short of goals at times, envious glances have been cast across town to where Robin van Persie - a summer target for City - has scored 22 times.
"United hit the jackpot with Van Persie," Kompany told the Daily Mail. "But you can’t think 'What if' about Van Persie. I am not sitting here thinking, 'What if we had signed Lionel Messi' either.
"His transfer has made a direct impact but to say he’s the reason we can’t make it - if it turns out that way - is not correct. I still believe we can do this but if we don’t, there will be plenty more reasons than the fact we didn’t sign one player and another club did."
