Saying old players are useless, I don't think it's right either, because when they sell players I believe that it has to do with the coach's taste of the criteria of the player he wants.
Not all old players are useless, but maybe I can just say the once chelsea is having are useless to the club, chelsea spent much money on the players they don’t need during the last transfer window. After spending much amount on players in the last transfer period, people were thinking chelsea will perform well, but we all saw how Chelsea played last season, we saw the position which they ended the season, all the quality players they bought performed poorly last season, I was just surprise to see player’s that Chelsea spent that huge amount of money on playing poorly on the pitch, no confidence, no team work, everyone was just playing individual ball last season.
What Poche did in my opinion was quite brave, because he made big changes with this new team,
If Pochettino didn’t make those changes in the club, then there won’t be any difference In chelsea performance, chelsea will still perform the same wey they performed under the previous coaches that they sacked. Even when chelsea was sacking their coaches anyhow, I knowthey needed a experience coach, but I knew their problem was not from the coach alone, we should also blame the players also. If Pochettino didn’t make the changes, chelsea might even get worst under him.
