Tottenham will begin their Europa League campaign against Georgian league champions Dinamo Tbilisi in the play-off round.
Andre Villas-Boas' side reached the quarter-finals last season before going out to FC Basel on penalties, and they were paired this year with the Georgians in the draw at UEFA's headquarters in Nyon.
Spurs actually played Tbilisi in the third round of the 1973/4 Uefa Cup, triumphing 6-2 on aggregate on their march to the final where they eventually lost out to Feyenoord of the Netherlands - a game remembered for the riots that took place after.
Capital One Cup winners Swansea reached the play-offs via a 4-0 victory over Swedish side Malmo, and they will face a two-legged tie against Romanian side Petrolul Ploiesti.
It is the first time they have played in Europe since taking part in the Cup Winners' Cup back in 1991, when they lost 10-1 on aggregate to an Arsene Wenger led Monaco side.
Spurs and Swansea will actually meet each other in the Premier League inbetween the two legs, when the two meet at White Hart Lane on August 25.
The first legs are due to take place o August 22 with the return fixture a week later, and victory would see the sides earn a place in the Europa League group stages, where they will join Wigan.
