David Moyes has accused Manchester City of showing a lack of respect to Everton in their chase for Joleon Lescott.
The Toffees have turned down two bids for the defender and boss Moyes is not happy at the way their cash-rich Premier League rivals are going about their business.
He told the Sunday Mirror: ''It's about showing respect and we're not being shown that. I'm sure if I was (City boss) Mark Hughes, with all the money he has, I would try to buy the best players.
''But we try to go about it in a different fashion. I would think I would go about my business in the way I've always done.''
City have had bids of £15m and £18m for Lescott turned down - and are now believed to be returning soon with a £22m offer.
However, Everton are insisting they will not sell the England international defender, even for £30m.
Moyes continued: ''I've always tried to contact the managers and show respect to them in terms of transfers - and no matter how much money I might have to spend I would always want to keep that up.
''It goes back to the managers having a drink together after the game, to the fact managers would still phone each other up when they are looking for a player. That is part of the way it should be done.''
