Though Chelsea was once again held in check 1-0 by Basel at the St Jacob Park Tuesday night, coach Jose Mourinho's troop can play the UEFA Champions League.
Mourinho's men rarely threatened and failed to have a single shot on target in the 90 minutes as Basel completed a shock double over the 2012 champions.
The winner came with just three minutes left as the hugely impressive Egyptian Mohamed Salah broke clear and slotted home past Petr Cech.
Qualification to the knock-out stages of the Champions League was the only consolation Chelsea manager Jose Mourinho could take.
But with Schalke drawing 0-0 at Steaua Bucharest, Chelsea are through despite their defeat, while Basel have moved into second and a draw with the Germans in their final match will see them through with the English outfit.
