Swansea City forward Wilfried Bony believes that the team need to make improvements following last Sunday's defeat to Stoke City.
Bony converted from the penalty spot to give the Swans the lead at the Britannia Stadium, but they eventually succumbed to a 2-1 defeat.
After the match, Swansea boss Garry Monk accused Stoke's Victor Moses of cheating after he won a penalty by going down in the box following minimal contact from Angel Rangel.
"We know that we didn't win so we are unhappy about that," South Wales Evening Post quotes Bony as saying. "We need to work harder, try to take the positive things out of Sunday and look towards the next game."
Swansea will take on Leicester City at the Liberty Stadium in the Premier League on Saturday.
