Sam Allardyce to field strong West Ham United side against Bristol City

West Ham United manager Sam Allardyce has claimed that he has 'no problem' selecting a full-strength side to take on Bristol City in the fourth round of the FA Cup on Sunday.

The Hammers, who are unbeaten in 2015, will travel to Ashton Gate at the weekend in the hope of reaching the fifth round of the competition.

"Bristol City are doing well at the moment in League One," Allardyce told reporters in this morning's press conference. "Several Premier League teams have struggled against lower league opposition.

"It's all about the attitude of our players. They need to rise to the occasion. I don't have a problem playing my full strength team as we've got a full week until our next league game."

In the Premier League, West Ham are seventh in the table.
