Aston Villa manager Paul Lambert has bemoaned his side's defending against Sheffield United after Ryan Flynn's late winner knocked them out of the FA Cup.

Nicklas Helenius had cancelled out Jamie Murphy's opener for the visitors, but Flynn's goal secured victory for the Blades.

He told reporters after the game: "We lost a poor first goal but we got back in to it with a really good equaliser.

"At one each you think we might have gone on to win it, but we haven't done it. The second goal was poor defending by us."

Lambert claimed before the game that top-flight managers could do without the cup "if they were being honest".
