Wenger's record against Mourinho is a dismal one.
"Is just the game, it is Arsenal, we don't think about how many points behind, is just Arsenal, is hard enough for us to be focused on other things".
Dunphy told Game On on RTE 2fm that he was impressed by the Gunners in their 2-0 victory over Spurs a fortnight ago and expects a similar display to produce a similar result.
Supporters will be desperate to see the Frenchman take the focus away from Mesut Ozil and put Arsenal's midfield on the back-foot by releasing players further up the pitch. It is Arsenal, and that is hard enough without us being focused on other things. "I remember coming to England in 2004; it was, for many years, Manchester United and Arsenal for the title", he said. "So we must focus on this".
Asked whether he sees himself as Borg or McEnroe against his old rival Wenger, Mourinho replied: 'I love tennis, I don't play tennis'.
Pogba's return to the side last month has galvanised their Premier League form, with Mourinho's men netting four goals twice in their last three league matches.
However, he has rejected claims that he is too conservative with his tactics in big away matches.
Phil Jones, Eric Bailly and Marouane Fellaini will miss Manchester United's trip to Arsenal due to injury.
"It depends with what you think about risk".
The Belgian global sustained a knee problem on worldwide duty in October but returned to action against Chelsea last month and had featured in each of the Reds' subsequent three games prior to Tuesday's 4-2 win at Watford, which he missed through injury.
"When Arsenal have the ball, we're going to defend with 11 players".
The manager is remaining hopeful, but up to the point of his press conference, he could not guarantee that Matic would be fit enough to play.
