Returning from the 0-1 loss to Dortmund in Germany, it seemed that Chelsea would easily pocket three points at St Mary's. However, James Ward-Prowse's super free kick in the first half of injury time made the visitors hate it. This is the fourth round in a row Chelsea have not won but the first defeat.

Southampton doesn't even have an official coach after sacking Nathan Jones. But interim coach Ruben Selles will make everyone remember him with this feat. Possessing only 39% of the ball, launching 13 shots compared to 22 of the opponent, but Southampton stood up to pressure from the opponent, especially in the second half.
