Manchester United's box office reunion with Jose Mourinho has lived up to the billing, with their former manager sent off as his Fenerbahce side denied Erik ten Hag a first Europa League win of the season.

The Red Devils have made a stumbling start to the new-look competition, with a shock home draw with FC Twente followed by an added-time goal saving them from defeat in Porto.

Christian Eriksen temporarily silenced Fenerbahce's febrile support but old foe Youssef En-Nesyri secured a 1-1 draw against a United side that have now won just one of their last 11 European games.

But this was the Mourinho show, with his touchline dramatics straying over the mark in the view of referee Clement Turpin as the hosts sought a spot-kick.

The Portuguese, who coached United between mid-2016 and late 2018, was sent to stands for his protests after Bright Osayi-Samuel was denied a penalty following a challenge by Manuel Ugarte.

Mourinho watched from behind railings as his side held out for a point as United blew a lead on a fourth straight European trip.

In London, Richarlison marked his first start of the season with a second-half winner to help Tottenham edge past AZ Alkmaar and earn a third consecutive win in Europe.

The Brazil international chipped home from the penalty spot in the 53rd minute, which ensured he avoided a post-match dressing down after he initially would not give the ball to stand-in captain James Maddison.

Ange Postecoglou made nine changes from the 4-1 win over West Ham United in the Premier League, but it didn't stop Spurs from clinching a seventh win from eight games.

Elsewhere on Thursday night, Glasgow Rangers enjoyed a 4-0 triumph at home over FCSB of Romania and Ajax Amsterdam beat Qarabag 3-0, who finished with nine men, in Baku.

Lazio were 2-0 winners over Twente in the Netherlands, while Eintracht Frankfurt, the 2022 Europa League winners, got a late goal from substitute Hugo Larsson to edge Latvia's RFS 1-0.

Olympiacos, last season's Conference League champions, saw off Malmo 1-0 in Sweden.

Another Greek side PAOK came from two goals down to salvage a 2-2 draw with Czech side Viktoria Plzen in Thessaloniki and Real Sociedad won 2-1 away to Israel's Maccabi Tel-Aviv in Belgrade, Serbia, due to the regional conflict.

Besiktas, Ferencvaros, Athletic Bilbao and Roma all won by the same 1-0 scoreline.
