Thomas Frank has warned his Brentford players against underestimating Barnet when the two sides face off in the FA Cup fourth round on Monday night.

The Dane is wary of becoming the second Championship scalp in as many rounds for the National League side, who saw off Sheffield United 1-0 earlier this month.

Frank is expecting his side to progress in the “battle of the Bees”, with the two clubs sharing the same nickname, after making it through round three with a 1-0 win over Oxford United earlier this month.

The victory is part of run of seven games unbeaten in all competitions, going back to before Christmas.

Frank said: “I’m looking forward to it. The FA Cup is special. We are playing against a team from the lower league live on television.

“A small ground with a sell-out. We are bringing 1,900 fans. Under the floodlights – it’s going to be fantastic. It would be a massive disappointment if you we don’t go through to the next round.

“Of course we respect Barnet and also the history of the cup. They have done well because the last five games they have been playing, they combine well in the final third.

“If we underestimate them then the same thing will happen to us as Sheffield United. The first 20 minutes Sheffield United were struggling. Barnet went 1-0 up and then they banked in a bit more.

“It will be a game where I expect us to dominate and control but there will be spells where we need to defend well.”

One player Brentford will face Barnet without is central defender Chris Mepham, who moved to Premier League side Bournemouth for a reported £12 million, a record sale for the Bees.

The 21-year-old Wales international broke into the first team in January 2017, having been through the academy since joining the club in 2012.

Frank is not concerned about finding a replacement, with players already stepping up with Mepham missing since going off injured in the club’s 1-0 win over Bolton Wanderers on December 22.

“First and foremost we can congratulate Chris,” he said. “He has done a top job here and all of us are proud, all the staff members who worked with and have been involved with him.

“It’s a record sale, which is a big thing for us. Of course he is a good player and would have found his way into the squad, but it shows Julian Janvier, Ezri Konsa and Yoann Barbet have done marvellously so far.

“We have some young players trying to push through – Mads Bech Sorensen and Luka Racic.”
