Ralph Hasenhüttl hailed his side’s performance after Southampton stunned top four-chasing Tottenham with a 1-0 win at St Mary’s.
Moving four unbeaten in the Premier League – and recording a third win in four matches – Danny Ings’s first-half strike was enough to secure all three points.
Digging in after the break to keep out José Mourinho’s side, the victory lifts Saints up to 11th in the table.
“We were always hoping to see such a home game from our side,” Hasenhüttl said. “Our side was absolutely fantastic and did a fantastic job today.
“Everybody was so sharp and put everything on the pitch, and this is the only way we want to play and how our fans want us to play.
“The only chance to take something against such a team is if you work like this. It’s the Premier League and you have to fight for every ball.
“Our behaviour against the ball especially was fantastic and we created a few chances, so it wasn’t undeserved that we won this game.”
Also keeping a second clean sheet in the last three matches, Hasenhüttl pointed towards his side’s growing confidence at both ends of the pitch.
“They’re coming more now. First at Chelsea and now again. It gives us a lot of self-confidence.
“It’s the first step in the right direction if you defend like a Premier League team and at the moment we are defending very well.
“We know we can always score with Ingsy up front. When he has a chance, the chance is big that he scores and it’s enjoyable to watch this team at the moment.”
