I would disagree with you about Kudus and Palhinha, both of whom have looked good in playing time so far. Both improve Spurs squad - I doubt if too many fans would agree with you
I didn't think that Tel had shown enough on loan to be a purchase at the level we needed him to be - imo Odobert has more experience (one season in top French league and one in PL with Burnley), and although frustratingly injured most of last season looks a better player than Tel. So whilst good forwards are neither plentiful nor cheap, so Tel being immediately available with 'great potential' had attractions, I'd have passed and looked for a better player (even if a top player not available directly after season ended).
IMO the Eze deal fell apart through lack of integrity on the part of the player and/or Palace - by all accounts Eze had agreed terms with Spurs and it was Palace delaying saying they wanted him to play tonight plus wanted to haggle over small items in contract as a delaying tactic. So all Woolwich did was to come in and agree to take similar terms to Spurs (or minimal change) in last few days whilst Palace/Eze stringing Spurs along saying 'deal still on, but it nedds to be after Thursday's match ......
That is unethical behaviour by business standards. Not criminal.
