Swansea City extended their unbeaten home record to 10 games with a 2-0 win against 10-man Stoke City.

The Swans took advantage of Wales international Sorba Thomas being harshly sent off for a second yellow card in the 36th minute.

Championship top scorer Zan Vipotnik lost his marker to glance in Josh Tymon's corner seven minutes after the restart.

Gustavo Nunes wasted a golden chance to kill the game off by dithering with 12 minutes to go but Liam Cullen sealed the win in style in added time.

The Wales forward intercepted a loose pass and lobbed goalkeeper Tommy Simkin from just inside the Stoke half, adding to the Potters' woes after they failed to take their chances in the first half.

It was goalless at the break with Swansea denied a reward for a fast start when Tymon's shot was smartly saved by Simkin.

The Potters responded and should have been in front only for Eric Bocat to have a shot cleared off the line by Josh Key before Lawrence Vigouroux superbly kept out Ashley Phillips' header.

Phillips' interference with the goalkeeper from an offside position then led to a Ben Wilmot header from a corner being chalked off shortly before Thomas' dismissal for a foul on Goncalo Franco.

The Swans have not lost at home in the league since the 25 November defeat by Derby County, the day after Vitor Matos took over, and have taken 26 points from a possible 30 in that unbeaten 10-game streak.

They sit 14th in the table, eight off the play-offs, while it is one win in 10 league games for Stoke, who are 15th with a 12-point gap to the relegation zone.

Thomas will hope for a happier return to Wales when hunting World Cup qualification later this month.

The 27-year-old, who is third for assists in the second tier, could count himself unfortunate to see red.

He was cautioned for a high boot and then had what looked an innocuous tangle with Franco, who went down theatrically.

It was a third key decision in a matter of minutes for the officials with referee Reubyn Ricardo failing to give what looked to be a clear free-kick to the Swans after a foul - by the booked Thomas - in the build-up to the corner for Wilmot's disallowed goal.

The offside flag correctly went up to end celebrations from the away end, with Vigouroux impacted by the actions of Phillips.

The sending off helped Swansea take control with Vipotnik – who had been limited to a free-kick that went a couple of yards wide in the first half – getting his 19th goal of the season when he lost Tatsuki Seko in the box.

Stoke showed spirit to stay in the game and could have salvaged a draw only for Bae Jun-ho to volley a tough chance wide in the 89th minute before Cullen's composed long-distance strike.

Swansea head coach Vitor Matos:

"It was a good performance. We started the game really aggressively and with intensity, good speed on the ball, positioning and counter-press.

"The red card gave us an advantage but then it is about having the right structure, mindset and discipline, which we did.

"The goal gave us a little bit of tranquillity and we kept the momentum for 70 minutes. Stoke reacted but we stayed calm to get the game back under control.

"The bench was really important and when you have Liam you can always score, which he did with a wonderful goal. It was beautiful with the right amount of speed and power."

Stoke manager Mark Robins:

"We had two unbelievably good chances to get our noses in front. We've got to take those chances and then we had a goal disallowed.

"Then it's compounded by Sorba having a yellow card that didn't look like one – how can you be penalised for trying to take a shot mid-air and somebody putting their head down?

"That put him on a tightrope and then, for all the good he has done, that loss of discipline can't happen if that was a kick out. He has given the game away.

"The goal that we conceded was really poor but we still carried a threat right up until the end. We need to lick our wounds ready for the game [against Ipswich] on Tuesday."
