A transfer window playing out exactly as you imagined is a privilege reserved for a select few at football’s top table.While the rest of the world responds to movements made elsewhere, the likes of Real Madrid, Bayern Munich and Manchester City can reasonably expect to secure most, if not all of their summer targets without many hiccups. And judging by how this window is unfolding so far, we may soon have to add Tottenham Hotspur to that shortlist.OK, that may be a touch optimistic, but Tottenham have operated like a club with serious intentions to compete for silverware and European qualification next season. With historic underperformance in back-to-back league seasons, this summer was always going to be a busy one, and Tottenham still have plenty of business to do in forward areas, where transfer fees are particularly inflated, and elite talent is not readily available. Still, their summer additions in defence and midfield with pedigree have set a strong precedent for what is yet to come.Yet, perhaps their most important addition in recent months remains head coach Roberto De Zerbi, whose marked shift in communication was at the heart of their successful efforts to stave off relegation. Without the Italian, it’s fair to say Tottenham would be in a different league, with a less glamorous list of transfer targets and short of a character with the charisma and cachet to land them.Roberto De Zerbi turned Spurs around in the final seven matches of last season (Alex Pantling/Getty Images)While his psychological revolution must remain central to Tottenham’s continued reversal of their protracted slide and habit of losing matches too easily, De Zerbi now has the talent at his disposal to display his tactical chops. Backed by the Lewis family, Tottenham have spent £185million on furnishing their engine room with two of the Premier League’s most in-demand midfielders, Sandro Tonali (£100m; initial £92.5m with £7.5m in proposed add-ons) and Mateus Fernandes (£85m), gazumping Manchester City and Manchester United, respectively, in the process.De Zerbi has typically operated with a double pivot across his managerial career, and immediately implemented that system at Tottenham despite previous managers Igor Tudor and Thomas Frank experimenting with alternatives in a desperate attempt to manufacture any on-field chemistry. So, having first impressed for AC Milan in a double pivot, Tonali will now join Fernandes to form a new-look midfield base with the technical, physical and tactical capacity to dominate matches in the Premier League.De Zerbi’s changes in midfield were the most important on-field adjustments over his seven-game spell last term. Tottenham evolved from a side that did not press well and could not progress the ball through the middle of the pitch through Frank’s miserable period and Tudor’s hapless interlude, to a side that tried to do exactly those things.
