Speaking to the club’s official website, Lambert highlighted the strength of the team he was up against:
“I don't expect anything less than a really strong West Ham team to come here.
"To be fair to Slaven Bilic he has picked really strong side every time they have been in the cup competition so I don't expect this to be an easy ride and I don't expect him to rest players.”
The last time the two sides met in the FA Cup was back in 2006, with West Ham winning 4-2; it was the year the Hammers went on to lose in the final to Liverpool.
Slaven Bilic’s side currently sit seventh in the Premier League, just a point off Manchester United in fifth place.
The Hammers will feel that they can give the FA Cup a good go due to the security of their league position and the fact that the squad has a lot more strength in depth compared to last season.
Although Lambert is wary of West Ham, he will feel that his side are capable of a cup upset due to home advantage and the incentive of a quarter final being just one win away.
