I have a theory about how it all went right for 3 or 4 years.
With the preparation and day to day building of the stadium,Levy`s time was so consumed with the build and counting his sheckles that after Poch`s 1st year,Levy took a step back and allowed a football person to run the football.Poch became manager not coach,he was seemingly involved in contract extensions (remember all the photos,arm around),perhaps not so much transfers??and Levy could spend his time going to travis perkins ordering sand and cement,choosing tiles,bathroom fittings.I doubt Levy had much personal or physical contact with the team during that period,poch was free to talk to them and motivate them.
Then as the stadium drew close to opening,Levy no longer had his days full,and reverted to type,sticking his nose in and rocking the boat.Poch drew back,making comments like when Sissoko`s deal was extended,"I dont know I am not involved in signings and contracts,a complete 180 on what he was saying the 3 years before.Eriksen and rose were fucked off told they werent wanted and played like that from then on,I seriously dont think that was pochettino,and also he was making clear he was back to coach with no say on such matters.
And there you have it,an investment property speculator thinking he knew better than a seasoned lifetime football professional,fucked poch off,fucked some of the squad off (i am not talking sacked or transefered at that point),As I say it`s only a theory,but the evidence holds up pretty well to me at least.
