Interesting point. Not something I had thought about in great depth I must admit re: Poch poor transfer acquisitions.If you look at Poch team selection over he last 2 or 3 seasons, the surprise has always been that most of the players were already at Spurs before Poch arrived - so whilst Poch has undoubtedly improved them his acquisition of new players since he has been at Spurs is definitely s mixed bag.
I'd suggest that Kane, for example improved a lot over the first 2 or 3 years under Poch but not much since, and the same with other players. So in total the squad has not improved that much in recent seasons as too few of the acquisitions have made it to the first team.
So I'd blame a failure to buy good players not over the last 2 or 3 seasons but all the seasons that Poch has been here.
This TW I've been pleased to see a combination of buying top rated players (Ndombele) some top rated youngsters (Clarke) and possible progression of youngsters (Parrott, White Tanganga) and I hope it works better than TWs even 4 or ,5 years ago - perhaps one of our best buys in that period was Dele who Poch was not involved in his selection.
Poch is a great coach but I have seen no evidence he's good at buying players (same as Southampton where he bought Osvaldo for the second time - Southampton had to cancel his contract at great cost,)
What I will say though is that he knows his system. He knows how to get us playing in an effective fashion. It is also hard to know who Poch wants in his team and doesn’t get. There may have been 3 or 4 players over the last 2/3 seasons who he has wanted in to actively improve the starting line up, but never got.
For the criticism of his potential poor transfers, there have been a few good ones in fairness.
As for Kane, he’s had a tough time with injury the last season and a half. I have high hopes for him for this season IF he can stay fit.
