Think you can really only comment on Lampard and Gerrard.
Gerrard - done a solid job in that he hasn't shit the bed, but given that he's been given more money than previous Rangers managers, and his contacts have enabled him to make some good loan signings (particularly from Liverpool - Ryan Kent amongst others) in a relatively poor league, you'd have to say it's about par.
Lampard - again did a solid if unspectacular job at Derby, but he wouldn't be anywhere near the Chelsea job if he wasn't....well....Frank Lampard. Be interesting to see how long the residual good will last if results don't go his way. I'd be concerned if I was a Chelsea fan, he's up against some elite coaches, and at the top level of sport, the one or two percent that can add matters.
Of the others....
Giggs - that Wales job basically relies on the fitness of Gareth Bale.
Phil Neville - Women's football is a different sport and managing in it requires a slightly different skill set than the men's game. Appreciate that might not go down well in some circles, but in my defence I played men's football for 20 years, and I've been coaching in the women's game for 10.
