Rashford was one of several United players who struggled last season and the 24-year-old even considered leaving his boyhood club after being left out of the team by interim boss Ralf Rangnick.
The England international has hit the ground running this season, however, scoring three goals and making two assists in six games.
Rashford scored twice as United beat Arsenal at Old Trafford on Sunday and Gunners legend Wright admits he could not begrudge the youngster’s brace following a difficult period in his career.
Speaking on the Ringer FC podcast, Wright said: ‘I was really pleased for Rashford because – it was the same as the Liverpool game – he’s another one of those players that everything he does is quite defining.
‘If he misses that [first goal], it goes to that place of real negativity again. But what I’ve seen from him up until this point, especially with the last two goals he’s scored, is somebody that thinks “If I’m going through, I’m scoring”.
‘I can’t complain about that because Arsenal went there with the right attitude.
‘Looking at Manchester United, in the current climate, you don’t want those players to get confidence.
‘But Rashford looks reborn, he’s putting the pot on the fire because he’s ready to cook. In that instance [running through on goal], he looks unstoppable.
‘The only thing that is going to stop him is if the pass isn’t good enough, or his touch isn’t good enough.
‘Both of the finishes got a little clip off somebody, but he’s getting the luck now. With his pace, he is f****** dangerous.’
Former Manchester United captain Roy Keane also singled out Rashford for praise after the Red Devils ended Arsenal’s 100% start to the season.
Asked what the difference was in Rashford’s performance on Sunday, Keane told Sky Sports: ‘Hunger, desire, the skill levels, the decision-making, stretching teams.
‘He has had a full preseason with the club, different [from] last summer. Now he looks settled, he is happy in his mind set and when Marcus is at it, he is a handful.
‘You don’t want to play against him because he causes problems. When he stretches teams he is a good player.
‘Today, he was outstanding, it was an absolutely brilliant performances. And I have been tough on him the last year or two. He needs to be more consistent but today, fantastic.’
Rashford, meanwhile, was delighted to help Manchester United secure a fourth successive win and climb to fifth in the Premier League table following a dismal start to the campaign.
‘It was a massive game,’ Rashford said. ‘They’ve had such a good start to the season and it was a big test for us today.
‘We showed up, we stood up to the challenge and we can all be proud of ourselves today. I thought it was an even game. There were big spaces in the first half but we didn’t manage to exploit them.
‘But, in the second half, we managed to exploit the spaces and that’s what made the difference.’
