Scott McDonald caused all sorts of problems for Rangers over the 90 minutes and scored two vital goals for his team, so he was deservedly my man of the match.
Even at the end, he was slowing the game down, taking the ball down to the corners and playing the game out.
Gary Caldwell was outstanding for Celtic. I think he only gave the ball away once during the whole game.
With the amount of challenges he made throughout the game, he made a huge contribution to Celtic hanging on to the 3-2 lead.
I can understand why McDonald didn't want to take the penalty, because he had made such a huge contribution to the game and, having missed one in the last match, he probably felt he didn't want to risk it.
I don't think it had anything to do with bottle - he's got plenty of that. He was playing well and Barry Robson had probably already decided he would take any penalties in this match.
"I think Celtic will go on and win the championship now on the basis of turning things around over the two Old Firm matches"
I think Whittaker really needs to take a look at himself after putting his team under pressure by being sent off in the 93rd minute of the match. It was unnecessary and Rangers have too many problems with suspensions and injuries to risk getting another player suspended.
While it wasn't a straight-red, it was still a silly challenge - he just took a whack at Shunsuke Nakamura and the ref sent him off, giving Walter Smith even more headaches with his squad.
I think Celtic will go on and win the championship now on the basis of turning things around over the two Old Firm matches and with the suspensions and injuries Rangers have built up.

In the second half, Rangers didn't get a look at Artur Boruc and I can't remember a save of any note he had to make in the second 45.
There wasn't a great number of chances for either side and, although people were saying Kirk Broadfoot was naive when he challenged Scott McDonald, it was magnificent forward play from the Australian.
He knew Broadfoot was coming, he got to the edge of the box and put the brakes on. Broadfoot then ran into the back of him and it was a stick-on penalty.
It was a great afternoon for McDonald. He scored two goals and he helped out with the penalty kick - and that made all the difference for Celtic - but the loss of David Weir was a big blow for Rangers.
"Gary Caldwell had a magnificent game and even when Jean Claude Darcheville came on for Rangers, they didn't get into an area where you could see them punishing Celtic."
Celtic rattled a corner off the post at one point in the second half, but they didn't really have too many chances.
But they kept pushing forward with a lot of wide play, they got corners, throw-ins and free-kicks and knew they had to win and they got the vital third goal and defended it.
Gary Caldwell had a magnificent game and, even when Jean-Claude Darcheville came on for Rangers, they didn't get into an area where you could see them punishing Celtic.
Over the 90 minutes, I would have to say Celtic deserved it.
