Swansea manager Paul Clement said he has been impressed with his side's belief since he took over for former coach Bob Bradley in December.
Swansea have climbed from the bottom of the table to 15th since Clement took over, capped by Sunday's cagey 2-0 defeat of defending champions Leicester.
Alfie Mawson gave Swansea the lead with his third goal in six games. Martin Olsson then got the crucial second in first-half stoppage-time, racing up from left-back onto Gylfi Sigurdsson's pinpoint through ball to smash a shot past goalkeeper Kasper Schmeichel.
Clement praised his team, and Mawson, after the match, saying: "His overall performance was very good, it's down to hard work on the training ground, instructions from the coaching staff and he had a good game.
