Basle have been hit by a UEFA disciplinary charge after their fans set off flares in Tuesday's Champions League match at Manchester United.
Marouane Fellaini, Romelu Lukaku and Marcus Rashford secured the hosts a 3-0 win on a night when the Swiss champions' fans made themselves heard from the outset.
However, the use of flares before the Group A opener kicked off has led to disciplinary proceedings being opened against Basle.
The case will be dealt with by the UEFA control, ethics and disciplinary body on October 19.
