The truth is that Pochettino is a better coach than both Lampard and Potter combined. Pochettino squad building and integration skills is not something that can brushed aside in the bigger scale. Also, Potter and Lampard got every media support before and during the chelsea job and failed miserably. Why is the media not giving Pochettino a chance at all?
It is too early to conclude Pochettino better than 2 previous coaches. His records aren't also very special, all the trophies he got when he was the manager of PSG only. He never won international competitions, all the trophies were local competitions in France. To be honest, I'm not really sure that Pochettino can easily improve the current condition of Chelsea. However, I agree that we must give him time and opportunity to manage Chelsea. We must understand why the media is not pessimistic with Pochettino, the media may consider his stats only.
