There are other reason behind the re-appointment of Frank Lampard to take up this job at this time, Chelsea right now is in a critical state, where if they miss out on this Champions League there will be no champions league for the club next season and Frank Lampard happens to be the only coach that got the experience of what Chelsea is facing right now in the champions league during when Chelsea was sometime in this kind of condition during Frank Lampard time as player in Chelsea.
Lampard had a bad result when he was managing chelsea. this is why so many chelsea fans are also feeling skeptical once he has become a guy that will be handling the club until the end of season. There are many reasons why it was happening.
As you can see that if chelsea was getting UCL again after lampard was going out from the club and the club was managed by tuchel. that proves that lampard is not as good as people think. he was chelsea's legend and yeah I do agree with it but he is still poor in managing a club like chelsea even though his win rate is not as bad as potter. Seems a bit better compared with bruno. The better thing for chelsea is to sack all of the teams that were already brought by potter from brighton to the chelsea.
I can only hope that lampard will be doing his best when he will be managing chelsea until the end of the season. Lampard just needs to learn about how to put a proper strategy like tuchel which was giving UCL and more trophies for chelsea.
