Seems harsh but losing a Championship playoff final does not qualify you for a job such as Chelsea.
He was however offered the job of his dreams within a year of becoming a manager so he was always going to take it.
In a decade he will probably look back and think that was silly.
Abramovich has to take some responsibility here for the same reason, I get that Lampard is a club legend as a player but where's the managerial apprenticeship?
Surely you should have to do more to earn these top jobs. If he'd have had success elsewhere he was always going to get the job one day so why not be patient?
Gerrard has been clever by going to a job where he had a 50/50 chance of winning the title early in his managerial career. When they close out the league this season he's put a huge tick in a box and the powers that be at Liverpool will obviously have noticed for future reference.
Arteta and Ole are in similar boats to Lampard, no managerial success of note at any decent level, they're under extra pressure and will be cut no slack. Fortunately for us at the moment Ole is doing very well!
But the proof is in the pudding at the end of the season, there's a reason it's been Klopp vs. Pep for the last few seasons.
Edit: I forgot to mention Lampard has a right to have expected a lot more from his 2 German forwards, especially Werner.
