"We lacked a bit of quality and were not quite at our best," he is quoted as saying by London24. "We had a lot of possession but lacked care on the final ball. But this is a tough league.

"We have a chance on Tuesday against Huddersfield to deliver a strong performance and remain in the mix."
Brentford follow up their meeting against Huddersfield Town with a trip to face Ipswich Town.
