I like Lampard and thought he was doing just fine, but he got his head turned by a Premier team, one which he played and broke records for so there was really only one outcome!
What he should have done was stay here for another season or two to learn his trade properly and see where it would lead him. The thing now is he'll only want to manage in the Premiership which he could do but he'll never win anything there. The top 6 now know he isn't good enough.
