The problem with taking the wrong job at the wrong time four times in a row means its a bit hard to evaluate him as a manager.Lampard was my choice for England manager. Average manager, perhaps, but half the battle is getting a team that likes you and will play for you. He has that in spades. I think he would have done as well as anyone. He did okay in his first season at Chelsea and wasn't given much of a chance to remedy a bad run in the second. Everton, well that was a basket case.
Chelsea is just not a team to have on your CV. Cursed.
