To put it simply, anyone who thinks that Pochettino is doing anything but a great job with us is dim. Poch single handedly changed the mentality, culture and style of this club with little help or resources. If anyone is going to 'get us to the next level' it is Mauricio Pochettino. Honestly my biggest worry is if he leaves is all of this going to fall apart and we end up going backwards. If it wasn't for Poch it wouldn't be the 'Big Six', it'd be the big 5 and we would be the best of the rest.
