A much-changed Tottenham side ground out a 2-1 win away to Hungary's Ferencvaros in the Uefa Europa League on Thursday.

Goals either side of half-time from Pape Matar Sarr and Brennan Johnson were enough to get Spurs their second win in two games in the competition this season despite a late Barnabas Varga consolation for the home side.

An inexperienced Spurs side made a slow start and Ferencvaros thought they had taken the lead in the 18th minute when Varga nodded home, but VAR ruled that there had been an offside in the build-up.

Spurs goalkeeper Guglielmo Vicario then displayed lightning-quick reflexes one minute later to claw out Varga's stabbed effort from close range.

The Premier League club grew into the match and broke the deadlock in the 23rd minute when Sarr was the only player in the Ferencvaros box to keep his cool.

The home side failed to clear the danger on two occasions before defender Stefan Gartenmann eventually lost his bearings and did not realise the ball was behind him as he ran back towards his own goal, allowing Sarr to pounce and slot home from inside the six-yard box.

The visitors had chances to put the match to bed in the second half, but Timo Werner could only find the side netting after rounding the 'keeper in the 64th minute and Johnson struck the crossbar from distance.

As Ferencvaros started to threaten, Johnson got his fifth in as many games with a left-footed finish that kissed the post on its way into the back of the net in the 86th minute.

Spurs needed the two-goal buffer as Varga directed a whipped cross past Vicario in the 90th minute to set up a nervy finale for Ange Postecoglou's charges.

Meanwhile, Chelsea marked their first-ever appearance in the Conference League with a 4-2 win over visiting Belgian side Gent.

Manager Enzo Maresca utilised his large squad, naming an entirely different starting XI to the one that played in the league at the weekend.

Renato Veiga headed Chelsea into the lead in the 12th minute, which Pedro Neto then doubled one minute after the interval.

Tsuyoshi Watanabe made it 2-1 in the 50th minute but two goals from Christopher Nkunku and Kiernan Dewsbury-Hall in seven minutes killed off the tie before Omri Gandelman scored a consolation.

A 44th-minute penalty by Michael Baidoo was enough to give Elfsborg a surprise 1-0 win at home to Roma, who sit on one point after two games. (AFP)
