FA Cup fourth round: Sam Allardyce sets his sights on Wembley glory for West Ham

West Ham manager Sam Allardyce insists his players can create history by going all the way in the FA Cup this season.

The Hammers have not lifted the trophy since 1980 and have reached the final just once since the start of the Premier League era.

They take on Sky Bet League One promotion hopefuls Bristol City in the fourth round on Sunday and Allardyce wants his side to convert their excellent league form into cup success this season.

"If it could bring success it would recreate modern history, particularly as we move into a new stadium," Allardyce said.

"I'm sure a lot of West Ham supporters have fantastically fond memories of what we did at Wembley when we got promoted.

"If we can get to a cup final, it's generally for most fans a once in a lifetime occasion."

Allardyce received heavy criticism last year for fielding a youthful side in the third round when they were thrashed 5-0 by Nottingham Forest.

The Hammers have no relegation concerns this season, however, and Allardyce insists his players can give everything to secure a place at Wembley.

"We haven't picked up as many injuries as we might have expected, we've got a full squad ready and raring to get stuck into the FA Cup," Allardyce said.

"I've got no concerns that it will affect the league form at all.

"The FA Cup falls on a Saturday, not midweek, so we have plenty of time between this game and the next game to recover and keep our very good league form up.

"We want to be very, very competitive in this competition. We know the glories of it.

"You have that ultimate goal of being at Wembley and that's one of the most wonderful things you can ever experience in your career."

Allardyce, however, is not expecting an easy ride at Ashton Gate against Bristol City, who are second in League One and have won their last six matches at home.

"FA Cup games are always extremely difficult against lower league opposition, particularly away from home," Allardyce added.

"It's all down to the attitude of the player. If they try to take things lightly, they can get caught cold.

"You have to start on the front foot because there is such excitement - players at Bristol City will play way, way above their best.

"They can produce a one-off performance that causes you a lot of problems."
