The Tottenham Hotspur midfielder produced a pretty non-existent performance against Anderlecht.
The pendulum swings once again for Mousa Dembele.
Not dramatically - but enough to prove why there may have been doubts about his role in the Tottenham team to start with.
Indeed, venture back a week and Dembele was being linked with a January move to Napoli by Tuttosport and needed a good performance against Liverpool to prove a point.
He duly produced one and fans and pundits alike raved about the Belgian playmaker, acting as though anyone who dared to doubt Dembele were almost committing a sin.
Then came an anonymous performance against Anderlecht, where - during a 2-1 defeat - the 28-year-old did absolutely nothing of note.
Is that exactly where the problem lies for Dembele - and has he proved, with that display, why doubts exist about his Tottenham place?
Plenty of Tottenham fans were frustrated watching Dembele against Anderlecht not because his performance was horrific but because it was so average.
It was like this was a different player to the one that featured against Liverpool.
In short, the 28-year-old is inconsistent. There isn't any point in a club chasing the top four playing someone each week if they aren't going to turn up every week.
With the player Dembele can be, he should be dominating games for Spurs every time - not when he pleases. And, without being too harsh, displays like this Anderlecht one sum up exactly why there is doubt over his role in the side.
