If you are the manager and you have real differences of opinion with the people making those decisions, or there are constant changes above you, then goodness knows how you can be successful, whoever you are.”Pulis believes De Zerbi would have sought clear guarantees from SpursReports indicate that De Zerbi has been handed plenty of power by Tottenham on off-the-pitch decisions, with the Italian expected to have a major say on the club’s squad building.Pulis has no doubt that the former Brighton boss will not have signed a five-year deal unless he has been given control of the club’s transfer targets.The 68-year-old added: “Looking at where Spurs have gone wrong with some of their player recruitment in recent years, I cannot believe that a manager of Roberto de Zerbi’s standing would sign a five-year contract without him having some say on signings and the new players who will be coming into the club.“With Spurs maintaining a strict wage budget, their recruitment must be smart and resourceful whatever division they are in, but it is also important it is in line with the coach’s needs and wishes.”READ MORE: Victor Wanyama vows to make Tottenham return and backs Roberto De Zerbi to thrive by compromisingThe post Tottenham Hotspur hierarchy changes have sparked struggles on the pitch, says Tony Pulis appeared first on Spurs Web.
