"But the most important thing is when the team wins".
Wenger added: "There is a lot of negativity".
Asked whether the Deeney comments had fired up the players, Wenger said: "You can not be a football player without pride". I know what I'm talking about because the same clubs contacted me and told me, when I met them, that their first objective was to have Arsene come.
We knew we're on a hard run at the moment, we had to look at ourselves and we had a big result in midweek in Milan and I felt we carried the determination into today.
"Did we move the ball more quickly? I don't know how much but of course it plays a part". He has now become the fastest player to record 50 assists in the Premier League (141 games), breaking Eric Cantona's previous record (143 games).More news: Toys 'R' Us considering closing United States stores

The victory over Watford does however mean the Gunners have won two on the bounce, having ended a four-game losing run with the 2-0 win over Milan at the San Siro on Thursday. In one week he goes from hell to heaven, and that's how life can be.
Arsenal opened the scoring on eight minutes as Mustafi powerfully headed Mesut Ozil's free-kick beyond Watford goalkeeper Orestis Karnezis, although Cech was required to deny Abdoulaye Doucoure and Richarlison on two occasions prior to half-time.
But the pair combined brilliantly for Arsenal's second goal with Aubameyang rounding the keeper to score after a defence-splitting pass.More news: Martin Shkreli sentenced to seven years in prison
With the Gunners 2-0 up at the Emirates, Ainsley Maitland-Niles conceded a penalty with a foul on Watford midfielder Roberto Pereyra.
"He had to wait a while to save a penalty first of all", said Wenger after Cech's first spot-kick save since 2011.
The victory was finally sealed 13 minutes from the end, when Aubameyang set up Mkhitaryan for his first league goal in an Arsenal shirt.
The former Chelsea goalkeeper had to wait nearly three months between his 199th clean sheet in the Premier League and his landmark 200th but he achieved it yesterday in some style, needing to save a penalty - his first for the club - and his manager hailed his goalkeeper's intense level of intelligence.More news: Mobile Version Announced with Cross-Platform Play with Nearly All Other Versions
