Every player will score pens for fun during training but in a game it is a specialised art, one that relies on total self belief and confidence. Yaya and Mario are examples of zero nerves. They knew they would score every time. Sergio, Jesus and Gundogan seem to have doubts and you can see the lack of confidence when they wait to take one. Two years ago Sergio would have easily scored yesterday as the keeper went really early and left the entire left side of the goal open but went for safety hitting it down the middle. I think it's time for someone to step up and demand the ball. I can't say who I think that will be, perhaps Rodri would be a good shout but it needs sorting soon.
