​Carlos Carvalhal has called for the introduction of video technology in the Premier League after Swansea were denied a penalty in their 1-1 draw at Newcastle.

The ​Swans had a decent shout for a spot kick after Mo Diame appeared to move his arm in the direction of a goalbound effort in the first half of the contest at St. James' Park.

Speaking via ​Sky Sports after the game, Carvalhal urged the relevant authorities to consider bringing in video assistant refereeing (VAR) technology for next term in a bid to end the uncertainty over decisions and teams missing out on crucial points as a result.

He bemoaned: "It's impossible from what I saw on the bench. I would not be honest if I said I saw from the bench. But of course, you know the technology these days, our assistant said it was a clear penalty.

"When I saw in the video, it was a clear penalty because the ball went towards the goal and he opened his arm, in my opinion, the arm is not in a natural position. When he opened the arm, it's a clear penalty and red card also. We are unlucky."

Jordan Ayew had fired the away side into a second half lead, but Joselu's equaliser on 68 minutes ensured that the points were shared between the Magpies and the Swans.

The ​Premier League's bottom club have now taken four points from a possible six on their travels under Carvalhal's guidance, and the ex-​Sheffield Wednesday boss explained that there was more to come from his side ahead of a couple of tough upcoming games.

He added: "In the last two away games, we've got four points, which is very positive. We are progressing, but it's not just the results. Today we had more possession than ​Newcastle, and had possession with intent to attack.

"We will make it difficult for them [Liverpool and Arsenal]. The attitude in all the games has been fantastic - they are upset today because they wanted to win, but we will give a good answer in these two games.

"We want to jump up positions. After the win at ​Watford, and now today, I believe that more people will think we can change positions."
