Man Utd 'unhappy' with Wrexham manager as Paul Mullin injury fallout continues

Manchester United are reportedly unhappy with Wrexham manager Phil Parkinson's fiery comments about their goalkeeper Nathan Bishop.

United continued their pre-season preparations with a 3-1 defeat to League Two side Wrexham at Snapdragon Stadium in San Diego, California on Tuesday.

United fielded a youthful side full of academy players, with their senior squad instead taking on Real Madrid in another warm-up match at NRG Stadium in Houston, Texas on Wednesday.

Bishop, 23, played the full match in goal for United and was involved in a nasty incident with Paul Mullin that left the Wrexham striker with a punctured lung.

Bishop collided with Mullin in the 12^th minute of the match but was only booked for his challenge.

Mullin required oxygen on the pitch and was forced off, with Wrexham later confirming he had suffered the serious lung injury.

Parkinson struggled to hide his anger after the match, warning Bishop to 'steer clear' of the Wrexham squad.

"It's a clumsy challenge from the goalkeeper, I'm disappointed with that. It should have been a straight red. If it's not denying a goalscoring opportunity, it's still a dangerous challenge," said Parkinson.

"So if you add the two scenarios together he should have been off the pitch. It's a dangerous challenge and obviously, Paul Mullin is our talisman.

"I'm fuming about it, I've got to be honest with you. It was a clumsy, reckless, challenge in a pre-season game and I'm not happy with it at all.

"I haven't seen the goalie and he's probably best steering clear of us for the time being because we're not very happy."

Bishop reached out to Mullin on Twitter after the match and apologised for the incident.

Mullin later responded by giving fans an update via his Instagram.

Posting a picture of himself in hospital, he wrote: "Thank you for all your messages! All good here!"

According to the Manchester Evening News, United are unhappy with Parkinson's post-match comments about Bishop.

The Premier League club feel the Wrexham manager 'unnecessarily inflamed the situation'.

United are concerned his comments 'could fuel online abuse towards Bishop after an accidental and non-malicious challenge'.

Wrexham goalkeeper Ben Foster, who himself used to play for United, has attempted to defuse the situation by passing Mullin's number on to Bishop so he can offer him a full apology.

"I feel so bad for Nathan Bishop though, he's absolutely heartbroken. I passed Paul's number onto Nathan so he can get in touch with him, but yeah he's absolutely gutted, I feel for the lad," Foster told The United Stand.
