Saints have an “amazing opportunity” to make it to the FA Cup semi-finals according to Mauricio Pellegrino.

Victory against West Brom has earned Saints a spot in the last eight, where they will travel to Wigan, who were shock winners against Premier League leaders Manchester City.

A semi-final spot and a trip to Wembley awaits the victors and presents Saints with a great opportunity to progress.

“For sure it’s an amazing opportunity for us in all different aspects but we have to think about one week at a time and be fully focussed and then we will see,” said Pellegrino.

Wigan’s win over Man City shocked the football world and Pellegrino added: “It was an unpredictable result for everybody but for this reason football is amazing.

“When you play 11 against 11 anything can happen.

“In tennis play the number one with the number 100 it’s almost impossible to beat the number one, but not in football. It’s a great thing. When a team from League One plays a Premier League team the fans believe they can win and it’s true.

“Maybe the chances are smaller but there are chances in one moment.

“When you play like Wigan did the other day anything is possible.”
