People think Pochettino can be a better coach than Potter and Lampard they are maybe right because we know Lanpard is not an experienced coach and he couldn't have a good performance in the last weeks when he was coaching Chelsea, while Potter also had nad performance in Chelsea and he couldn't even get fired in the first weeks.
Maybe Pochettino can help Chslea to improve their performance and get better place in the table for the next season.
