Indeed, the pundit and former United midfielder was livid with how bad Louis van Gaal's side were against Liverpool in the Europa League.
And he was incensed that no Man United players made enough effort to tackle Lallana.
Scholes told the Mail during a post-match conversation with Jamie Carragher: "It wasn't so much the quality of play, it was more not laying a finger on them that got me wound up. Not tackling? Adam Lallana was taking the p*** when he was rolling his studs over the ball in the second half! Why didn't someone just tackle him?"
Many are now raving about Lallana's ability and form. The 27-year-old has come on leaps and bounds over the last few weeks and, for once, got his pre-game talks to the press spot on this time around.
Several times last season, Lallana would promise a Liverpool win in a big game - ending up one of the worst players out there when the Reds duly lost.
This time, however, the playmaker promised revenge against Manchester United and that's exactly what Jurgen Klopp's men delivered.
Klopp is no doubt a big reason behind Lallana's improvement. The midfielder looks better physically, technically and tactically. Most of all, however, he is no longer shying away when things aren't going his way.
