Tuesday’s success also means they are now in a position to qualify for the round-of-16 for the second time in three seasons, with a draw against Schalke in Germany next month all they now require.
“Everyone knew it would be historic for us if we could beat Chelsea twice and I think we wouldn’t have deserved just a draw,” Yakin said. “It will be a nice final match against Schalke. That is what we worked for and we will try to qualify for the knockout stages.”
Even if Basel lose in Gelsenkirchen, they are guaranteed the consolation of dropping into the Europa League next year.
