The playmaker wasn't terrible in his native Belgium but was far from the fantastic performer that turned up against Liverpool on Saturday.
Indeed, any concerns about Dembele's Tottenham role were justified on Thursday night, because the 28-year-old's consistency just isn't there.
Against Liverpool, fans and pundits alike raved about the central midfielder. Here, though, any one of his competitors for a first-team place would have put in a better, more imposing shift in the middle of the park.
A Dwight Gayle-esque performance from the Tottenham youngster, who couldn't fill the Harry Kane void up front.
Njie will come good with time and has already shown promising glimpses at White Hart Lane. But he is yet to net and it won't be any easier to do so in the Premier League than it would have been in Anderlecht.
The forward committed a number of fouls and earned a booking - his only real contribution of note to this Europa League clash.
For Anderlecht's second goal, the right-back was beaten far too easily. And, just a couple of months into this Spurs career, the 25-year-old is already under pressure after some sub-par performances.
Last season, Trippier's form for Burnley quite easily matched up to Kyle Walker's. Back then, Walker was actually doing very badly indeed.
So, considering the fact the full-back has been brought in to challenge Walker, it's been a misfire so far for Tottenham. The first-choice right-back will be delighted - but Mauricio Pochettino won't be as far as Trippier is concerned.
