An important point to consider is that in the latter half of last season the Premier League race had already been sacrificed in favor of cup competitions. This season, the players and coach should be playing at level to be competing to WIN the league. The results should be significantly better.
Kudus, Kolo, Simmons SHOULD have improved the team - but Spurs have hired a coach who prefers caution and only commits players to attack in set pieces. In open play, more often than not the only pass on in the final 3rd is a backwards pass.
Coaching Brentford to finish top half is an entirely different beast to coaching a team to WIN the league and Cup competitions.
I cannot fathom why Spurs hired him after having some success with an attacking coach. (5th, Semi Final, European Champions). Spurs should have built on this and hired another attacking coach and strengthened the squad to provide better capabilities to cover for injuries.
Frank has hit a big problem. The more the team loses, the more cautious his tactics become and the less risks are taken. Even at 1-0 down to Chelsea with 10 minutes to go, Spurs didn't commit any players during attacks, and our forwards were outnumbered 3 to 1.
