Nahki Wells is confident that he and his Bristol City team-mates can be equal to the task when they lock horns with Millwall in the Emirates FA Cup this month.

The two Sky Bet Championship rivals were pitted together at yesterday’s fourth round draw and will do battle at The Den on a date yet to be confirmed for the right to meet either Premier League side Sheffield United or League One outfit Plymouth Argyle on the road in the next round of the world’s oldest competition.

“Millwall is a common competitor obviously them being a Championship side, so we are well familiar with what to expect with the players that they have and the challenge that they will bring,” Wells told The Royal Gazette.

“Disappointed that we haven’t got a big club, but it’s another team that we know we are capable of beating to progress to the next round. So we just have to get through our fixtures and approach that fixture with supreme confidence and belief that we can beat them.”

City advanced to the fourth round after edging Portsmouth, the 2008 champions, 2-1 at Ashton Gate on Sunday.

Famara Diédhiou and Chris Martin were on target for the home side while Callum Johnson replied for the visitors.

“Obviously it was a good cup tie against a really good League One side who really matched us evenly over the course of the 90 minutes,” Wells said.

Millwall advanced via a 2-0 win against hosts Boreham Wood at Meadow Park 24 hours earlier.

Meanwhile, City’s cup-tie against Portsmouth was their first taste of action for the year as their January 2 fixture away to Brentford was postponed in the Sky Bet Championship.

The win was a first for Wells and his team-mates since edging Wycombe Wanderers 2-1 in the Championship on Boxing Day.

“Delighted to get the win after we have been going through a really tough period,” the Bermuda striker added. “It gets that winning feeling back, gives some people confidence and the two strikers scored, which is always a positive.”

Dean Holden, the City manager, made one change to his squad for Sunday’s FA Cup tie against Portsmouth from the one that lost 2-1 away to Luton Town in their previous outing in the Championship on December 29, with defender Alfie Mawson returning from a knee injury in place of Wells who came on as a 66th-minute substitute.

“I got some minutes, came on and played a little out of position on the right,” Wells said. “But I did what I had to do considering we’ve got a very thin squad at the moment.”

City are back in action tomorrow in the Championship when they travel to Brentford for the rescheduled fixture that was postponed earlier this month.

Holden’s team are tenth in the league standings, four points adrift of a spot in the promotion play-offs.
