Frank certain Brentford will bounce back strongly at QPR on Wednesday after Barnsley shock

Thomas Frank has promised that QPR will face the backlash after Brentford surrendered their proud unbeaten league record.

Sunday's shock 2-0 home defeat to Barnsley ended a run of 21 undefeated games for the soaraway Bees, who missed the chance to go back to the summit of the Championship.

"I am in no doubt that they will come flying out on Wednesday night, " said the Brentford boss of his side.

"I have just said to the players that we lost to a better team today and it is all about how we react to that and we need to bounce back against QPR,

"Whenever we play QPR it is a big game – whether it is a relegation battle, a middle of the table game or when one team is high in the table.

“It means the world to both clubs’ fans and what an opportunity for us to bounce back against them."

Frank had no complaints about a first league defeat since a visit to Stoke City in October, admitting his side were second best for once.

"Barnsley deserve a lot of praise," he said. "We have been so consistent for 21 games, but at the end of the day we lost it fair and square.

"There were a decisive few moments – if Josh Dasilva and Saman Ghoddos had scored their shots in the first half then it may have been different. And then we made a mistake for them to go 2-0 up, they scored and it’s a different game.

“There was no lack of effort from the players, they put everything out there and there was a big determination from all of them. We are in such a good place, but we lost to a team who made it difficult when they hit their high level.”

Frank added: “I am frustrated we lost but not frustrated overall. For me it was inevitable it would happen at some stage – we knew that. We just hoped that today wouldn’t be the day.

"We had hoped to go one more game, one more game, one more game. But we know in this league you can lose to every team in this division, even if you are at the highest level.”
