On Sunday, the Gunners clinched their first league win at Old Trafford in 16 years, with Pierre-Emerick Aubameyang’s second half penalty enough to separate the teams.
Arsenal had lost three of their last four league fixtures ahead of their trip to Manchester but produced a solid performance to inflict another defeat on struggling United.
Wright described Arsenal’s victory as ‘massive’ and reserved special praise for defender Gabriel and midfielder Partey, who joined the club last month from Atletico Madrid.
‘It’s a massive win for Arsenal. The thing is that since Mikel has been there, there has been progress,’ Wright told Premier League Productions.
‘He has got the players he’s got to work with and it’s changed in terms of defensively, intensity, the culture and what he’s trying to do.
‘We saw as well with some of the players – Gabriel, on a booking in the first half and the way he played was brilliant, [Thomas] Partey as well.
‘He’s slowly going to integrate the players he wants to play the system he wants to play.
‘What we’ve seen is the organisation of Arsenal, something that people have spoken about when it comes to a lack of intensity and lack of drive. We aren’t seeing that anymore.
‘We have got a guy up front [Aubameyang] who if he gets chances will finish them and it’s a whole different structure at Arsenal.
‘They can talk about not beating that top six as much as they want, we are going into a different era.’
Arteta, meanwhile, says he is ‘delighted’ with his Arsenal team after they ended their dismal run at Old Trafford and climbed to ninth in the Premier League table.
‘I wanted to generate belief and I asked them to be who we are as a team right now,’ Arteta said. ‘I’m delighted because we played with a lot of courage and big personality.
‘They played a really tricky formation with four midfielders and two that constantly strain your back four.
‘We could have scored twice in the first half and when we scored the goal we had to manage those moments. There was high stress, it is different to any other ground.
‘Individually you have to win the fights and step up to the occasion and the performance of every player today was top drawer.’
