He is 5-3-1 with 2ppg (also 2 ppg in PL). Under Solskjaer this season, we were 7-3-7 with 1.41 ppg (1.42 ppg in PL). We've been disappointing, but not humiliating. This is while the team is just about as unsettled as ever (Lingard, Pogba, and Martial have more than one foot out the door, Cavani wanted to go to Barca but didn't get his move, etc.).
We have not been great under him, but it's certainly been better. This may be more of a reflection of how poor Ole was considering that RR hasn't exactly had a great managerial career himself. In any case, it was the right decision to bring an interim instead of letting Ole drag on his mess.
