Nasri is believed to be on the verge of a £25 million move to Manchester City, a transfer that will ensure Arsenal do not lose the midfielder for nothing in 12 months' time. However, Mancini had hoped to sign Nasri by the end of the weekend, only for the deal to be delayed by the reported demands of the player's agent.
As a result, Arsene Wenger started Nasri in the weekend loss to Liverpool, and he claims he is not worried about picking him again for Wednesday's Champions League qualifier in Italy. Should Nasri feature at all during the 90 minutes, he would become ineligible for City's European campaign this season.
Mancini remains convinced the deal can be tied up imminently, but he did warn Arsenal and Nasri to seriously consider the consequences of playing in Udinese.
"I think we can close in the next two days, but if he plays in the Champions League, it will be a big problem," Mancini said.
"It's a big problem because we have followed Nasri for 40 days and I have hoped it [would be completed] in two days or in three days. I am sure we can close this in 24 or 48 hours, but I don't know why it hasn't been closed."
Asked if he could look elsewhere if Nasri becomes cup-tied, Mancini replied: "It could be possible, yes."
