"Losing Leigh Halfpenny is a big blow. He is one of the best defensive 15s in the world - it was a big knee to take in the face. Hopefully he will be OK.
"But Halfpenny's penalty kicking is such a big part of Wales' gameplan. There was a penalty just before half-time about 50 metres out and Dan Biggar had a look and thought 'that's out of my range'. Halfpenny would taken that on. That's the difference."
