Swansea

Cardiff, Swansea and Wrexham will find out who they will play next when the fourth round draw is made at around 22:00 BST on Wednesday, following Arsenal’s televised third-round tie at Port Vale.

There are seven Premier League sides in the hat so far – Liverpool, Chelsea, Brighton, Crystal Palace, Brentford, Fulham and Wolves – along with Wycombe Wanderers, of League One, and League Two club Grimsby Town, who knocked out Manchester United in round two.

As well as the Arsenal tie, Manchester City are in action on Wednesday at Huddersfield Town, while Newcastle United host Bradford City and Tottenham Hotspur are at home to Doncaster Rovers.

There is a decent chance, therefore, that Cardiff, Swansea and Wrexham could face heavyweight opposition as they look to reach the quarter-finals.

There is also the possibility, of course, of a Carabao Cup Welsh derby.

Swansea claimed their most memorable cup triumph in recent memory against Forest, coming back from 2-0 down to shock the Premier League club thanks to two goals in stoppage time.

Alan Sheehan’s side had no time to celebrate, however, with a tricky league trip to Birmingham City to come on Saturday (12:30 BST).

The likelihood is that Idah will be back among the substitutes at St Andrew’s given the form of Zan Vipotnik, who came off the bench against Forest to score his fifth goal in his past five Swansea appearances.

“That’s the best problem to have,” Idah said.

“Zan has been in fine form and hopefully that continues.

“We all want to get to the Premier League and we are all in it together. I think the competition we have in every position is brilliant. If we are all pushing each other, that’s a good start.”

Ange Postecoglou says his Nottingham Forest players got too “comfortable” after Championship side Swansea scored twice in stoppage time to knock them out of the Carabao Cup.

Two first-half goals from Igor Jesus had put the Premier League side firmly in control of their third-round tie.

However, a Cameron Burgess goal gave the Swans hope and, in a stunning finale, Zan Vipotnik levelled before Australia international Burgess scored his second to send the 2013 winners into the last 16.

“We had to finish them off and we had plenty of opportunities to do that, and a couple of decisions didn’t go our way,” said Forest boss Postecoglou.

“I think the lads got a bit comfortable in that moment and you’ve got to know the warning signs.

“Players just thought it would naturally finish that way and we’ve paid a heavy price for that. We need to improve.”

The former Spurs boss had promised this would be the night fans started to see his imprint on the side he inherited from Nuno Espirito Santo at the City Ground.

Instead, Forest conceded three for a second game in a row under Postecoglou, who added: “Tonight was a great opportunity for us to progress in a cup and give ourselves an opportunity to that success – and to let it slip is hugely disappointing.

“But it doesn’t change anything – we understand some of the things we have to work on.”
