Sandro Tonali to Spurs: Italy midfielder's speed, dynamism and technical quality could be key for Roberto De Zerbi

Tottenham's deal to sign Sandro Tonali from Newcastle continues an exhaustive overhaul under head coach Roberto De Zerbi. At £100m, he becomes the most expensive, and the most important, of six summer signings so far.

The view from Newcastle is that they have secured an excellent fee. Tonali was of course a key player for Eddie Howe but struggled to find consistency last season. The club have nearly doubled their money on the Italy international in the space of three years.

Spurs, though, will feel confident he can justify the expense under a head coach with whom he has connections. Tonali started his career at Brescia, in the city where De Zerbi grew up.
