Hamann slams ex-Newcastle pal Shearer for Allen criticism
"Shearer wouldn't know about passing a ball because all he did was finish," said Hamann to the Liverpool Echo.
"He did a good job of putting it in the net but he never needed to pass a ball backwards or sideways.
"It's rubbish to say Joe Allen only makes easy passes. You need players who keep the team ticking over and ensure that you keep possession,
"What he has done for the football club so far has been great. I'm not sure any other player would have had the impact he's had.
"The fans are talking about Allen and rightly so because he's been outstanding. Shearer's remarks won't make me change my mind."
