The moment Micky went down and Royal came on for him, it was just a matter of time before Udogie got his second yellow.  With no BJ to help him out and no pace next to him, it was bound to happen.  I really think we might have gotten a result with 10 men.  Heck, we almost got a result with 9 men.  Their last 2 goals don't mean anything.  Even a team playing full strength that's going for the equalizer will concede these goals, much less playing with 2 players down.
Cuti had that card coming.  He got away with one when he kicked Colwill.  And we were up a goal too, so didn't make any sense.  Udogie was lucky too he didn't get a red when he got his first yellow.  Both feet off the ground and studs showing.  Very immature for a player that had only 9 yellows across 60+ matches in Serie A.  In hindsight, a red for Udogie at that juncture might have meant Cuti playing a little more carefully, but it is what it is.
I also don't know what to make of the tactics, especially after Udogie's sending off.  We saw how Liverpool kept us at bay with ease when they went to a low block with 2 players less.  I don't know why we didn't do the same. 
In any case, credit to the lads for the fight.  This is not a shabby Chelsea team.  It's just a shame that on Poch's return to the Lane we shot ourselves in the foot.  I really would have relished a full strength battle with them and I think we would have come out on top.
