As nicknames go, it is one of football’s most unusual. Luis de Barros Lopes’ father had it before him.

The 22-year-old attacker, powerful and fast, gave the visitors a torrid time throughout and now has his sights set on making an impact in what he reckons is the most important game of his career as he considers putting in a call to his former Benfica B team-mate Jota, now starring with Celtic, to discuss how to unpick the Ibrox defence.
