I think maybe because they thought they could go for fast goals
against Watford. Also, somewhere in the game, Chelsea switch to
3-4-3. With more players upfront, it did make sense in a way to
pump up the field where more players were. Maybe they were more
eager/desperate to get a goal quick knowing the pressure was on to
win the match. Since Man U had won earlier and it was Warford
afterall? Dunno, just maybe.
And what was Kalou doing? Chelsea could have scored earlier if he
had let a cross to Drogba instead of taking it himself. And it's
not the first time he's done something like that either. I remember
in the match against Sheffield he scored, but after he did so,
Ashley cole seemed angry Kalou didn't leave the ball to him. Other
than that, I realise when Kalou has the option to shoot or pass, he
would always shoot. Unlike Drogba who would hold up play and very
often play the ball to his team-mates. Hard working Kalou may be at
times, but Drogba he is not. Even Sheva who is constantly
lamblasted for not scoring does his best to play the ball to team
mates as well.
I say, who needs Kalou?
