Watford boss Walter Mazzarri was in a friendly mood following his side's 3-1 win over Jose Mourinho's Manchester United on Sunday.
The managers do not share an amicable history and have previously crossed paths during their time working in Italy's Serie A.
In his post-match press conference, Mazzarri was asked whether he will have an after-match drink of wine with the Portuguese manager: "If he has time we will do it.
"We spoke before the game - even one day next week we can go out for dinner."
Mazzarri was at the helm of Sampdoria and Napoli when Mourinho was Inter Milan manager between 2008 and 2010.
