After such a prolific season last term, Rashford believes he could hit 40 goals if he can stay fit in the forthcoming season.
“Before last season, I always said let’s get to 20 – for a winger a good benchmark,” he added. “But this season, I’ve hit 30 so we have to try and push it now and go above and beyond.
“Towards the end of the season, I was struggling with a few injuries, and I probably wasn’t quite at it – that’s when the goals started to dry up a little bit.
“If I can keep that side of it under taps, I feel like I can go on and get 35 or 40.”
United look well placed to finally start challenging again under Ten Hag’s strict regime.
Rashford felt the force of the disciplinarian last season when he was dropped from the starting XI for the game at Wolves after being late for a team meeting.
The forward came off the bench to score the winner in a 1-0 victory, but revealed he was just one minute late.
“I learned from pre-season, a couple of the lads were late and it was important to implement his rules there and then,” said Rashford, who also “100 per cent” agreed with Ten Hag’s decision.
“I wasn’t even that late – I don’t think he was being harsh, late is late – but it was probably about 45 seconds, a minute late.
“I already knew what was going to happen because of the rules he implemented in pre-season.
“I am not going to sit and argue about it, because we’ve got a game to win. There is a time and place to speak to him, but if we win the game nobody really cares.”
