Brentford manager Dean Smith was disappointed with the nature of the two early goals his side conceded.
"With the quality that they have they don't really need a helping hand but unfortunately we gave them one with a two-goal lead," he said.
"We're not renowned for that - defensively we're normally very good.
"We came here with a game plan but when you give away goals like that it goes out the window. There were good things as well - we competed well enough."
