Southampton defender Jack Stephens has hailed the impact of Manolo Gabbiadini.
Stephens said the decision to sign Gabbiadini was already paying off.
"It's been a great start for him and hopefully he will carry on that form," said Stephens after victory at Sunderland. "You can't argue with what he has done so far.
"The second goal came at a really good time, just before the break. I would imagine it really put Sunderland on the back foot. The timing more than anything was important, but it was a fantastic goal."
