I think you have to say he got the tactics right for the start of the match, considering how we dominated the first half. Had it not been for De Gea's brainfart or had we been a bit more lucky with the finishing, we would have gone into half time in the lead.
We struggle a bit with containeing their strikers, but I can't criticise Ole for picking Lindelof ahead of Bailly. Bailly is not great in the air either and he is very inconsistent and rash himself. It's by no means guaranteed he would have handled DCL and Richarlison better.
Now for the second half, I have different views to the rest. For the first 5-10 minutes the game was just scrappy and both teams were trying to find a rhythm. A lot of fouls were breaking up the tempo. Martial started drifting out of the match at 60-65 minutes, with Bruno now doing way more pressing/running and even playing more advanced. Where we really retreated were the last 20 minutes, after the subs.
I think Ole made the wrong subs, with the power of hindsight. Mata really struggled in midfield and we missed the combativeness of McT. In physical games, when teams press us, Mata is the wrong player to bring on. If McT needed taking off, for rest, I would have brought in Pereira on who's at least a bit of a shithouse and presses/tackles/fouls a lot in midfield. He suits an RM position of a diamond way, way more than Mata. Up front Martial and Greenwood were both poor, so it's a crapshoot about who to take off so I can't blame him keeping the more experienced and mature player on the pitch.
Overall, I think Ole did well today but question marks remain over his subs. They rarely pay off and they more often than not make us even worse than we were.
