Gary Neville does not expect any club to come close to such a price and believe United may have the edge on City by offering players in part-exchange.
“It’s difficult,” Neville told Sky Sports.
“City don’t tend to break their budget do they, £65m/£70m [is their transfer record] – they’re not going to get him for that.
“So it’s whether they could get a player to Tottenham that would makeweight the deal. And I think that’s what United maybe have in Martial, James and Lingard.
“They’re types of players you could send there [to Spurs] plus a chunk of money and it might make Daniel Levy happy, I don’t know.”
