I wanted to wait for you to see for yourself before I replied. The run of games playing Huddersfield, Fulham (4 times?
), Cardiff, etc, gave you lot blind optimism when Ole took the wheel. Didn't help that the totally uncharacteristic wins against Juve, Spurs and PSG reinforced the blinkers.
You didn't just have a bad day against Wolves. That is basically the extent of your abilities this season (blame Jose, training, injuries, individuals, whatever). Think of Barca as basically playing Wolves again but with Suarez, Messi and Dembele/Coutinho instead of Jota, Jiminez and the other one.
And after saying all that I sense you will beat them. Call it a hunch.
