Swansea manager Michael Laudrup saluted the resilience of his side as they twice came from behind to defeat Wigan 3-2 at the DW Stadium.
Roger Espinoza and James McCarthy struck for the home side, but Laudrup's men responded through Angel Rangel and Itay Schechter before Dwight Tiendalli hit the winner 14 minutes from time.
With Wigan battling against relegation, the tension was evident in a nervy first half, with Laudrup admitting Tuesday night's contest was not the best game he had witnessed.
He told Sky Sports: "The reaction and the intensity my players showed in the second half was really great.
"It wasn't a great football game, technically speaking, because there was too much at stake for Wigan.
"I think coming back twice in an away game to Wigan like this, I can be very, very pleased."
Meanwhile, Laudrup confirmed keeper Michel Vorm would fly back to south Wales despite being stretchered off after a nasty clash of heads with Ben Davies.
