Trent, retread back to our own half, in line with the rest of our defenders, Dalot enters our half, at walking pace, not a foot away from Trent, literally could had been holding hands at that point, and Dalot makes the run and gets passed him, and Trent is no where to be seen. Dalot makes the cross into the box that leads to the header that ends up going backwards.
Trent didn't block or recover anything in that sequence. He blocked the shot from Fernandes, that was following the chance that Hojlund had, when he was caught out with the ball over the top down his side.
Like I said, he was ok at best in that first half, his passing was off, but he wasn't winning anything to begin with in that half. He got catastrophically worse in the 2nd. He's had plenty of good games this year, including in the defensive side of the pitch. That first half wasn't one of those.
