Chelsea lost to Swiss side Basel for the second time in Champions League Group E after a late goal from Mohamed Salah snatched the win.
Despite the loss, Mourinho's side progress into the knockout stages of the tournament, but Sky Sports expert Niall Quinn was less than impressed with the performance and says the big clubs don't fear Mourinho's men.
Quinn said: "It wasn't a great message to send out tonight and to be outfoxed by the manager Murat Yakin twice in this campaign will hurt Jose.
"I think there was a speed out of the traps from Basel which he probably expected but he'll be disappointed with the way his players handled it because it seemed to go on and on and they never really got hold of it.
"They knocked it around a bit better in the second-half but not enough to suggest that this was the performance of a big European powerhouse that was just having a bit of an off night and will come roaring back.
"There needs to be a little bit more happen for Chelsea for the big sides to fear them."
Goalscorer Salah, as in the previous fixture at Stamford Bridge, was hugely impressive and Quinn thinks Jose Mourinho might have his eye on the Egyptian winger.
"There was a shot of Jose making some notes, I wonder whether it was his name going down in his notebook?
Salah and his whole team had the desire to things at a much higher pace than Chelsea and it was a joy to watch his performance.
"Frei and Serey in the midfield for Basel outshone the star names for Chelsea that we usually think are way above the norm and that has to be worrying regardless of tiredness."
