Brentford’s Thomas Frank says his side need to find ‘better solution’ in trying to break down defensive sides after the Bees EFL Cup penalty shoot-out exit.

Cambridge's Harvey Knibbs' sudden-death penalty won it for the Us after Brentford's Marcus Forss cancelled out Marc Richards' third-minute opener.

A side boasting nine changes from the weekend’s win at Middlesbrough should have had enough to beat their League Two opposition but Frank’s men failed to capitalise on the lions share of possession.

The League Two side's reward for beating one Championship outfit is an away trip to another, Swansea.

"We showed a lot of willingness in the first half but it didn't really click,” said the Dane.

“The second half was much better in terms of passing the ball and moving it quicker but I expect us, even when we're playing against a back five, to create more because a lot of teams have one game plan when they come here.

"We need to find some better solutions to create even more chances but it's not always easy for even the best sides in the world. We can and will look at how we create more chances.

"We wanted to win and go through but it's always that balance between keeping players fit and getting minutes into them. We had players more than capable of winning the game but it just didn't happen.

"It was a classic cup game between a minor side and a team in a higher division. We dominated but they got the early goal and banked up defensively.”

Brentford host Hull in the Championship on Saturday.
