Ten-man Tottenham recovered from an early setback to start their Europa League campaign with a commanding 3-0 victory over Qarabag.

Despite Radu Dragusin's early red card, goals from Brennan Johnson, Pape Sarr and Dominic Solanke helped Ange Postecoglou's side to a third straight win in all competitions.

Just seven minutes had elapsed when the hosts were reduced to 10 men as last-man Dragusin dragged down Juninho after he was caught in possession.

However, Spurs responded brilliantly to take the lead just five minutes later, with Solanke stealing possession and feeding Johnson, who applied a neat first-time finish.

The hosts survived a scare before the break when Juninho steered wide from Elvin Cafarquliyev's cross but doubled their advantage seven minutes after the restart when Mateusz Kochalski helped a corner into the path of Sarr, who instinctively volleyed home.

Qarabag squandered a great opportunity to halve the deficit just before the hour mark when Toral Bayramov's penalty hit the crossbar after Yves Bissouma tripped Cafarquliyev.

Tottenham capitalised in the 68th minute as Kochalski parried Son's shot into Solanke's path and he put the game beyond the visitors, who were denied a consolation later on when Juninho's header was disallowed for offside.

Data Debrief: Spurs soar despite Dragusin's historic early bath

It had the potential to be a difficult night for Tottenham when Dragusin was shown a straight red card - Spurs' earliest in a major European match.

The defender also became the first Tottenham player to be sent off on his European debut.

Spurs recovered to take control of the contest, though they survived a scare when Bayramov hit the bar with Qarabag's first missed penalty in the Europa League after six consecutive successful kicks.
