It's for AP to decide and if the designated penalty taker doesn't feel confident at that very moment, he himself may decide to give the ball over to someone else who can do the job. I guess it's what happens in most clubs.
Great result and nice to see that two of the players who were rested on Tuesday got on the scoresheet, which also tells about AP's apparent very sound squad management IMO.
I'll take an ugly win anytime, especially in the situation we're in. The sooner we get in the + points, the better and when we get in some sort of comfort zone we may start thinking about sexy football.
