Why ?
Why can't people say it wasn't a great performance ?
I know we have very high expectations these days, but our finishing tonight was poor, 26 shots on goal, 14 on target, and we scored 3, that's not a great tally is it ?
There were some good performances, Lewis, Grealish, and Rodri, Alvarez and Bernardo when they came on, defence were mostly OK. However we allowed a pretty shite team to give us a game, and after their equaliser, we were hanging on a bit for a while.
We shouldn't be using the pitch as an excuse, there was nothing really that I noticed that was more difficult, and it's not like we don't play in the rain much either.
At the end of the day, the result is all that matters, and we won (easily in the end), but good performance (by our standards) it wasn't.
Any away win in the CL is a good "result", but I don't see the point painting the performance for something it wasn't. In the second half, we only gained control of the game by bringing on Alvarez and Bernardo imho.
