Not sure he made much difference when he was here.
Set pieces haven’t been much of a problem defensively for us probably since Silva, most of the managers have been pretty good at organising them. The issue has been offensively, we had a few slight purple patches under Ancelotti and Dyche where we scored a few, but other than that it’s been nothing.
In fairness to Charlie Adam he devised the Beto goal v Liverpool at Goodison and then we’ve never seen a trained move ever since. Absolutely classic Everton.
