Chelsea hero Graeme Le Saux is convinced Rafa Benitez can make history with the club in the remaining weeks of the season.
Benitez has steered the Champions League holders to the Europa League Final against Benfica this month.
Le Saux, 44, said: "The opportunity to become the first club to hold both trophies in the same season would be an amazing achievement.
"And to be one of only three other clubs to hold all four major trophies would be marvellous and should motivate the players."
