Rashford, on the back of his best goalscoring season of his career last term, has netted just once in 16 matches so far this campaign.

The 26-year-old has not scored in his last ten games, and was slammed by Erik ten Hag last week for going out to celebrate his birthday after their 3-0 hammering at the hands of rivals Manchester City.

Parker, who made 105 appearances for the Red Devils between 1991 and 1996, has hit out at Rashford again, after previously describing him as ‘selfish and petulant’.

Parker told Bettors: ‘Marcus Rashford doesn’t bring anything to the team and I said the same thing last year, when he scored all these goals between November and April. He was never a good player, he was a goalscorer.

Former Manchester United player Paul Parker has insisted that Rashford was ‘never a good player’

Parker said that United ‘are not being rewarded’ for what they have invested in Rashford – after the England forward penned a new five-year £300,000-per-week deal back in the summer

‘People were calling me a traitor, they were calling me bitter, but this is not about bitterness. After that period with all these goals scored, people went mad with telling the club they should give him a new contract and tie him to the club.’

Rashford scored 30 goals in all competitions last season and was rewarded in the summer with a new five-year deal.

He signed a five-year contract worth £300,000-per-week that would keep him at the club until 2028.

Parker said that United ‘are not being rewarded’ for what they have invested in him.

He said: ‘Man United rushed to give him loads of money and now they are not being rewarded for what they invested in him. In any industry, you should be rewarded for consistency but he was rewarded after a few months and since then it has just been erratic.’

Parker’s comments come after Rashford hit out at fan channel The United Stand to ‘stop spreading malicious rumours’ in response to a video which questioned whether his Old Trafford future was in doubt.

Well known fan channel The United Stand then published a video on Monday titled: ‘Rashford’s future in doubt?’

Faz from the United Stand in the video said: ‘He’s travelled with the squad but not been used (against Fulham). To travel with the squad all the way to Fulham not to be used is very interesting and I’m not buying it.’

He added: ‘I think it might have been a form of punishment from Erik ten Hag. At the moment everyone can agree Marcus Rashford’s body language when he’s going to games, he doesn’t look like he’s happy.

‘I don’t know if he fully wants to be here. Where his commitment is. Does he really want to play for Manchester United?

‘The numbers he put up last season – it’s a big change. How can you go from a 40+ G/A (goals and assists player) to the level he’s at now.’

Rashford was left out of the squad against Fulham with an injury but was all smiles as he returned to training on Tuesday following his rocky week.

It’s uncertain though whether he will play a part in United’s important Champions League clash away at Copenhagen on Wednesday night.
