When Tyrone Mings inexplicably gifted Club Brugge a penalty in the Champions League group phase in November, Aston Villa manager Unai Emery labelled it "the biggest mistake I witnessed in my career".
On a night of redemption for the England defender, Mings returned to the scene of his howler - and helped Villa take a huge step towards the quarter-finals of European football's most prestigious competition.
"I was more than happy to come back here and play in this stadium again because I think we had unfinished business," Mings said after Villa's impressive 3-1 win at Club Brugge in the last-16 first leg in Belgium.
