Inter Milan's Holland midfield star Wesley Sneijder is ready to join Premier League champions United while Atletico Madrid striker Sergio Aguero - Diego Maradona's son-in-law - is close to signing for FA Cup winners City.
City, meanwhile, are close to clinching a deal for Aguero, which would pave the way for the departure of leading goalscorer Carlos Tevez to Spain or Italy.
Although Atletico were previously reported to be holding out for £50m, it emerged last night that Atletico could be willing to accept £40m - and City have the cash ready.
City manager Roberto Mancini and his squad were already heading for a pre-season tour of California last night. But the Italian is being kept abreast of negotiations.
Aguero would be City's first major signing of the summer and is likely to be followed by the arrival of Arsenal's Samir Nasri for £25m.
