Maybe we don't practise heading in training.im not going to blame players for that but who do you blame then? I think out of the last 5 or 6 games we have conceded goals because we are not making defensive headers. Have a look at the goals if you don't believe me. Same up front how many headers do we win in the box? Very few or if we do they are weak or rarely on target. Tha needs to go to spec savers if tha dunt see how weak we are in the air.
