Saw most of Oliver's game.  No major problems that I noted although there were signs of it getting a bit tetchy towards the end.
The 2 main VAR referrals were a possible offside for Atalanta's 4th goal and a check for a penalty for handball by an Atalanta defender but both onfield decisions stood. The Valencia players were frustrated they didn't get the penalty but the replays were not all that clear. To me it didn't look like handball.

It was good to see Oliver talking to players and until the penalty incident there was little dissent.

Decision making seemed sound and the AR's did well with a couple of close offsides.

Only 1 YC I think for a pull-back near the touchline by an Atalanta player.  They did commit more fouls than Valencia but I can't say I noticed PI by any one player.

I don't think there was anything for Oliver and his team to lose sleep over but as a non-referee I'd be happy to read any other opinions.
