Everton boss Ronald Koeman heaped praise on new signing Jordan Pickford after the goalkeeper played a key part in Saturday's season-opening win over Stoke City.
Wayne Rooney scored the only goal as the Toffees overcame a sluggish start to register a hard-earned 1-0 win at Goodison Park.
The result would have been different had Pickford not produced a stunning stoppage-time save to deny Xherdan Shaqiri, leaping to his left to push the Swiss star's goal-bound drive around the post.
Pickford's save preserved a clean sheet on his first Premier League appearance for Everton, a feat the 23-year-old also achieved on competitive debut in the Europa League.
"We know we brought in a really good goalkeeper," Koeman told Sky Sports.
"He dominated his area today, he's still young, and he had a great save on that [Shaqiri] shot. That's really important."
Despite the victory, Koeman admitted his new-look side was affected by nerves against a determined Stoke.
Hard @premierleague opener, nervous from our side. But the most important were the three points. Also a clean sheet! #Everton #EFC pic.twitter.com/0htIne3iuv

The visitors created the better of the first-half openings before Rooney's goal swung the momentum firmly into Everton's favour.
"It wasn't a good performance from our side," the Dutchman said.
"But it's the first [game] that has maybe brought nerves to the team and maybe some of the new signings.
"If you know that and you keep a clean sheet, you keep the three points at home, it's a perfect result."
