Speaking on Sky Sport (h/t Sport BILD), Hamann said: "There have been several situations this year where Neuer was responsible for goals or where he was lucky, like in Bochum when Kim Min-jae cleared the ball off the line. That means when you play balls over the top of the defence, his timing let him down on one or two occasions."
The former Liverpool defender also analysed Neuer's performance against PSG in the Champions League. "On Tuesday he had two or three situations where the whole stadium held its breath and there was no need. It was absolutely unnecessary to take such a risk there."
Lastly, he had some piece of advice for the Borussia Dortmund forwards ahead of this weekend's Der Klassiker. "It’s definitely something when you have four fast players up front, where you’ll get one or two chances.”
