De Ligt had to leave the match on three separate occasions because of a head injury, and unfortunately, on the third occasion, Pinnock capitalized on his absence by scoring a goal.
Manchester United boss Erik ten Hag explained his fury with match officials over Brentford's opener during Saturday's 2-1 win.AdvertisementAdvertisement"He was okay, that's what he told me," Ten Hag said. "That's what I asked him when he came off: 'Is there a problem?' No, he was 100 per cent there, not any time (was) there a doubt to take him off.
"I wasn't furious, but I just was asking my player how he is. He said 'it's just dry blood, it's not bleeding', so we are really surprised that he has to come off."
Ten Hag continued: "Of course, there was a huge moment, because Brentford are very good in corners, and when you then miss one of your best headers, and they take benefit from it, then of course you are disappointed."
