Brentford boss Thomas Frank insists they face Chelsea tomorrow night as rank underdogs.

Frank has reminded everyone that on the day they were winning promotion to the Premier League, Chelsea were beating Manchester City in the Champions League final.

"This is the big picture of the difference between our clubs," said the Dane.

"But we are here to be an addition to the Premier League, and the best way to do that is by bidding, pushing and trying to attack them. We will try to do that as much as possible on Saturday.

"It is a team with the highest quality and world-class players in all positions. They have one of the best coaches in the world and I do not think there is a weak point. But we love that challenge and we can't wait."
