Assured and composed, Gunn helps Saints to their first clean sheet under Hasenhuttl.
Gunn was a £13.5m signing from Premier League giants Manchester City in the summer.
After his display against Chelsea, Hasenhuttl has confirmed Gunn will be starting against Derby County in the FA Cup on Saturday.
“I think he did an amazing job,” former RB Leipzig manager Hasenhuttl said after the game. [H/T the Daily Echo]
“He is a very offensive defending goalkeeper and that is what I need against a team that is always playing the chipped balls behind the last line.
“I was aware of them and we knew that they have good deep runs and this ball is very hard to defend for centre backs so we need a keeper who is on the jump and defending forward, and there were a lot of situations where he saved the ball.
“He is a very talented goalkeeper and I want to give him two games. This was the first and the second is against Derby County in the FA Cup.
“I think he deserved to have a clean sheet.”
