Having suffered a loss to Basel in September in the opening game at Stamford Bridge, Chelsea boss Jose Mourinho commonly known as "The Special One", warns basel about the improvement of his troop as both parties are set to clash tonight at St Jakob-Park.
Basel, meanwhile, sit third, one point behind Schalke, and to advance must match the German side's result against Steaua Bucharest before going to Gelsenkirchen and winning.
Mourinho therefore relies on the current status of the Swiss side to scare them ahead of the meeting.
"If somebody has to feel the pressure, it's not us," Mourinho said. "It's Basel, because they are in a limited situation to qualify for the next round.
"They are under pressure and we are not. We can finish the job to qualify and Basel, even if they win, have to play a last final at Gelsenkirchen.
"For them, the situation is difficult. This shows clearly that, after the first match, we did our job and they didn't do theirs.
"This Chelsea is better than the Chelsea that played at Stamford Bridge.
"Hopefully we can continue the good run we've had in the Champions League and finish the job."
