SWANSEA boss Brendan Rodgers hailed the effect of Gylfi Sigurdsson after the Iceland midfielder scored twice in their 3-0 win at Fulham.
Sigurdsson scored either side of half-time to set the Swans on course to victory, which was confirmed when Joe Allen struck late on.
Swansea now sit eighth in the Premier League and Rodgers was quick to praise the on-loan Hoffenheim midfielder, who joined in January and has now netted four goals in three matches.
"He has slotted in perfectly and he is a wonderful lad," said Rodgers.
Roberto Martinez declared his Wigan side were too good to go down after they were held to a 1-1 draw by West Brom.
The Latics dominated proceedings at the DW Stadium but could not claim their second home win of the season, with Wigan old boy Paul Scharner cancelling out James McArthur's goal.
The Wigan boss said: "It's a really frustrating feeling and you feel it is a football injustice but today I really enjoyed the performance."
West Brom boss Roy Hodgson was happy to admit his side were second best.
"Wigan played very well," he said. "It was obviously a very important game for them to win and they certainly went about it in the right way, they committed a lot of players forward."
