I'm not sure Ole got a lot wrong today. The team picked itself considering the schedule and the rotation involved. Who do you play instead of McFred against Liverpool's press? VdB who couldn't impose himself against Leicester? Matic who can no longer run? Pogba who got outrun by Roma while playing in a midfield 2? At the end of the day, Ole is working with who he's got. Just like when he was picking Perreira and Lingard. We can say that Greenwood should've started instead of Rashford, but Mason just played 120 mins in the last 5 days, so there is logic to keeping him on the bench.
We started well, got the goal we deserved. But even then you could see the problems. McT won a fair few balls high up the pitch but never even tried to pick out the forwards who were making runs. Liverpool's first big chance came when Shaw couldn't make a simple ball down the channel to Pogba. When your best technical player makes that kind of mistake you know you're in for a bad night. But Dean did his job and we were safe.
Their first goal was a freak of a goal with Pogba falling on the ball which prevented Shaw from clearing it. Unlucky, but these things happen. The second goal should've easily been dealt with by Pogba at the far post. Ole isn't telling Pogba not to do his only job at the end of the half. The third goal is a complete embarrassment by Fred, Shaw and then Dean. Lindelof didn't cover himself in glory while trying to block the shot either. When multiple players screw up in quick succession, what can a manager do?
His substitutions were also logical. Greenwood was our only attacking sub and nearly scored. He knew the risk of putting Pogba in midfield but had no choice. The Matic sub at the end was to have another passer on the pitch to provide a long ball into the box, true hail mary stuff at the end of game. Bailly was also booked. It didn't work out, but you can see the reason why it would be made.
We can use hindsight to say Ole made wrong decisions but they have logic to them. Another day they could've worked, today they didn't. A lot of our fans, including me, wanted us to go at Liverpool today. But at the end of the day, football matches are won in midfield and our midfield 2 can't hold a candle to Liverpool's. Unless Pogba suddenly falls in love with defending or Matic grows new legs, the only way to move forward is to get new midfielders. That's what the summer window is for. We can only hope that we get them.
