Liverpool midfielder Jordan Henderson says they won't underestimate FA Cup semifinal opponents Aston Villa.

Under the guidance of new manager Tim Sherwood, the Midlanders have won four of their last seven Barclays Premier League outings - including a 1-0 success at Tottenham Hotspur last time out.

Henderson told liverpoolfc.com: "Aston Villa are doing very well, especially of late, they've had some good performances, good results. Away to Spurs last weekend they won 1-0, so they'll be high on confidence and want to cause an upset.

"They've got some good players, so it'll be a tough game - a very tough game. How many times have you seen the underdog win, especially in semi-finals and finals? We will need to be careful of that.

"But if we do our job properly - which I'm sure we will - and we give everything with the quality that we've got, then we can really hurt them. Hopefully on the day, it's our day."
