Rangers were beaten over two legs by Osasuna in the UEFA Cup round of 16 on Wednesday.

But UEFA were concerned by the behaviour of a minority of Rangers supporters during the match in Pamplona, with offensive songs clearly audible.

Rangers were fined £13,000 by UEFA last May as a result of their supporters' "discriminatory chanting" during the Champions League last-16 tie against Villarreal.

The fine came with a warning that further instances of sectarianism would not be tolerated, yet the problem has not been fully stamped out, despite the club's widely praised efforts.

Infantino told BBC1 Scotland: "If sectarian singing would still continue then UEFA would certainly take measures as it has in the past.

"UEFA has even excluded a Dutch club (Feyenoord) from the UEFA Cup earlier this year because of the behaviour of the fans of this club."
