It's just invented reality at this point. Decided to dig into that claim and do some fact checking.
The only evidence I've found on transfermarkt of injuries to every squad player in 2014/15 (Poch's first season, fair to say "the start) are; Bentaleb (Ankle) Walker (surgery from a pre-season injury) Davies (shoulder) Mason (Hamstring) Lamela (Calf) Lloris (knee). All of those were short lay-offs bar Walker but hardly seems fair to pin that on Poch, and oh! look! Only 2 muscular injuries! In fact Lamela's best period of availability for Tottenham Hotspur after his cursed first season were Poch's first two seasons.
Can you tell me with a straight face that 6 injuries over the course of an entire season amounts to "loads"? Who have you been discussing this with? The ministry of utter bollocks?
I do believe you made that up
