Chelsea manager Jose Mourinho has insisted that he is not worried about a laser pen attack on him during his side's Champions League clash against Steaua Bucuresti on Wednesday.

The Portuguese boss and Oscar and Eden Hazard had a laser pen shone on them by a visiting fan at Stamford Bridge during the Blues' 1-0 win in Group E.

"I was aware of it, but I cannot be worried about that when the game is going on," The Mirror quotes him as saying.

"I don't know if it creates any kind of problem, and during the game I felt it a couple of times, but not big. I felt the green laser, but I felt no pain, so I kept going."

The Metropolitan Police have confirmed that a man has been arrested in connection with the incident and has been taken to a West London police station.
