RALPH Hasenhuttl criticised Saints’ defending after their dramatic FA Cup exit, admitting: We must do better.

Saints came from behind to lead 2-1 through goals from Shane Long and Danny Ings, only to concede twice in the last 15 minutes.

Hasenhuttl said: “We couldn’t defend how we wanted to which was very disappointing for me because being strong for 75 minutes is not enough.

“We gave it away too easy. That’s the reason we lost this game.

“[Giving away leads] was a bigger topic last season but it’s hard to understand why in some moments we stop doing what we do best.

“We’ve had a very intense time in the last few weeks but to be a top-six team we must learn to win such games.

“This is something we can do so we must be self-critical. It’s not enough for us, we should not be happy. That is our best chance to get better.”

Jose Mourinho admitted Saints were the better team but Hasenhuttl responded by saying: “That’s nice but it doesn’t help me. Any football game is not about being the better team, it’s about being the winning team.

“It’s easy for him to praise us but they are the more clinical team because at the end in the last 15 minutes they turned the table.”

The decisive 87th-minute goal was not without controversy but VAR upheld the referee’s decision to penalise Angus Gunn for bringing down Heung-Min Son, who dispatched the winner.

Hasenhuttl added: "I don’t want to discuss it, we’ve had so many discussions about VAR. This is a job for him to look at it, to decide yes or no. I don’t care about the referee’s decisions, it’s more important to me for our next step what we did right or wrong.”
