This result has put the Swans in complete control of playing in the Premier League next season, with seven games left and now 36 points in the bag. However, this match was not a walk in the park for Swansea. Villa were able to outshoot the home club 12 to 10 and even placed one more shot on target than the Jacks.
However, a header from Fernández early in the second half was enough to secure a crucial three points for the Welsh club, earning him a strong individual rating in the process.
Match-winners all round at the back
Lukasz Fabianksi (7): The Polish international goalkeeper faced 12 shots in the game, however only two of them were on target. Still, he had to stop both and did so well as he kept the Swans' narrow lead intact.
Angel Rangel (6): He ran a lot in the match, but defensively was beaten a few times. He was fortunate that his centre-backs bailed him out, and that they were facing the ineffective Villa.
Ashley Williams (7): The captain was busy in this match, keeping the composure of the defence when Villa started to attack. He did have some nervous moments in the box, but for the most part he performed well.
Federico Fernández (8): Similar to Williams; he was a force in the middle cleaning up messes and not allowing the Villans to get off a clean shot. He managed to score the winning goal too so that gives him an eight.
Stephen Kingsley (6): The Scottish defender struggled in the first part of the match. However, as the game carried on he settled down and put in a decent performance until he was subbed off in the 86th minute with an injury.
Mixed bag in midfield
Ki Sung-Yeung (4): The South Korean international struggled to find his footing in this match. He was subbed off at halftime due to an injury, but his presence was not missed on the pitch.
Leroy Fer (6): The Dutch midfielder showed flashes of what can can bring to Liberty Stadium next year. However, he had an uneventful shift and committed three fouls in the process.
Gylfi Sigurdsson (7): He did create three shots in the match but none of them were on target. However, his set piece delivers were accurate and he assisted the goal with a terrific delivery. American international goalkeeper Brad Guzan did his part as well by completely missing the ball as he attempted to punch it out, but the placement from Sigurdrsson created the confusion.
Jack Cork (6): At times he struggled with the physicality of the Villans' midfield, but he did put in a scrappy effort in the match. His activity drew three fouls but this game was clearly not one of Cork’s best.
Lack of cutting edge going forward
Modou Barrow (6): He kept on making runs at the defence but Barrow’s pace was not able to create that many problems for Villa.
Bafetimbi Gomis (6): The French striker was lost at times in the match. A lot of that had to do with the consistent pressure from the defence. He did manage to get off two shots, but none of them threatened Guzan.
Solid impact off the bench
Leon Britton (6): He came in and brought tenacity, controlling the game for the Swans in the centre of the park.
Kyle Naughton (6): The full back was brought in the match to help secure the 1-0 lead and possibly start a counter running down the flanks. He did a decent job in the 12 minutes he played.
Wayne Routledge (4): He played for less than five minutes and picked up a yellow card in the process.
Guidolin's men grind out the win
Francesco Guidolin (6): The win gave him the passing grade, but the performance for the Swans was poor. His decisions on the substitutions were not the best as he failed to put more pressure on one of the poorest defenses in the Premier League.
However, the Swans pick up three points and are one step closer of playing in the top flight next season.
