Frank Lampard believes it will be a tough ask for Chelsea to win the Quadruple this season.
Jose Mourinho's troops are currently battling for four trophies as The Blues are contending for the Premiership, FA Cup, Uefa Champions League and in the Carling Cup final.
The England international knows the club could still win everything, but thinks it may be one bridge too far to surpass Manchester United's feat in the 1998/99 season.
"It will always be possible while you're in them," Lampard told Sky Sports News. "That has to be the aim. When you're in competitions you want to win them.
"It's possible in that extent. It is tough to fight on all fronts and win all of them. That would be asking a lot. Maybe too much, you don't know.
"In our minds we want to try and win all four. If we fall short fair enough, but we know we'll have given everything."
