Brentford boss Thomas Frank is eager for his side to keep focused following their Carabao Cup semi-final defeat to Tottenham Hotspur in midweek. 

The Bees have the chance to put the 2-0 defeat to Jose Mourinho’s side behind them on Saturday, as they host Middlesbrough at the Brentford Community Stadium in the third round of the FA Cup. 

The two sides have already met earlier this season, as Neil Warnock’s side escaped from London with a point after a 0-0 draw in November. 

And, after leading his side to a historic maiden cup semi-final already this season, Frank has had his appetite whetted by the chance to test themselves against the country’s elite sides. 

“First and foremost we are proud that we made history, I’m very proud of that and the way we performed throughout the tournament,” the Dane said.  

“We played against five Premier League sides and I think we competed in all of them, and should make us more hungry, and give us more determination and give us a bigger desire to develop and go forward. 

“We all have big ambitions and we all like to be facing these challenges every single week, but we can only have one focus, and that is the FA Cup game against Middlesbrough that we would like to win, so that’s the focus.” 

Brentford have been in incredible form heading into the New Year, with the Bees currently on a streak of 15 Championship matches without defeat - a run which saw boss Frank named Manager of the Month award for December. 

And, after a first loss in over two months at the Tottenham Hotspur Stadium, they will be looking to immediately bounce back against Boro and progress further in the competition with a win. 

Frank will be absent from the tie this weekend after testing positive for Covid-19 this week, with Brentford B head coach Neil MacFarlane the man in the dugout.

And MacFarlane will be without Josh Dasilva for the weekend’s clash, after the midfielder was reprimanded by VAR in midweek as he saw red for a tackle on Pierre-Emile Hojbjerg, meaning he will have to sit the next three games out. 

Pontus Jansson is also a doubt for the third round clash after suffering a minor injury earlier in the week, while Shandon Baptiste continues to sit out after knee surgery. 

Things are even worse for Boro, who will be fielding a youthful team for the clash after a Covid-19 outbreak among the camp. 

With a number of first team players unavailable, Neil Warnock has had to turn to his under-23 side to fill the gaps in his team for the trip to the capital.   

"I want to play as many first team lads as I can, I think 50% of the squad will be under-23s and it will be supplemented with first team lads,” the Boro boss said. 

"I actually picked the team last week for the game and it's completely different now. That's all changed over the weekend and Monday and Tuesday.

"I want a performance. If we get beat we get beat, but I want the lads who are playing to show me what they can do.

"Why should we forfeit it? It's the greatest cup in the world. It gives other people a chance to play they can always say they played in the greatest competition in the world.

"I want us to go and enjoy it and see the lads who haven't been playing regularly on top of their game."
