Hull head coach Marco Silva said he had always believed in match-winner Oumar Niasse after the substitute's two goals secured his side a win against relegation rivals Swansea.
iasse had failed to deliver at parent club Everton after arriving from Lokomotiv Moscow in a £13.5million deal, but was drafted in on loan by Silva in January and his two second-half goals sealed three crucial points.

Swansea defender Alfie Mawson headed home in stoppage time to ensure an anxious finale, but Hull held on to climb to within one point of safety.
"We tried to find solutions in the (transfer) market to help our team and Niasse was a player who was different to our other strikers," Silva said.
"He's one player to come here and help us. He feels as well that we believe in him and that's important for him and the other strikers."
Silva played a master-stroke by sending on Niasse for ineffective midfielder Alfred N'Diaye in the 63rd minute.

Niasse fired Hull ahead six minutes later after racing on to Abel Hernandez's pass and slammed home his second from inside the area in the 78th minute.
Swansea head coach Paul Clement said the first-half withdrawal of both Angel Rangel and leading goalscorer Fernando Llorente had been a major blow.
"The injuries hurt us," said Clement, who also revealed defender Martin Olsson had been forced to limp through the closing stages. "The fact you have to make two changes is never ideal.
"It's not down to who goes on and who comes off, it's more that in the second half a coach wants to have those options to be able to make changes.
"At a goal down we made an offensive change and then our left-back also gets injured and you're playing with 10-and-a-half players. It did have an impact."
