Where might Tottenham need to strengthen?

Winning the Europa League to secure Champions League qualification was a huge boost to Tottenham's finances but also meant the squad will need strengthening if they are to hold their own against Europe's elite.

New boss Thomas Frank has only had two weeks to consider where improvements are necessary.

He gave the green light to a £30m move for forward Mathys Tel, who has joined after a loan spell from Bayern Munich, while defender Kevin Danso's stint on loan from Lens has been turned into an obligatory £21m deal.

The only other arrival has been 18-year-old Croatian defender Luka Vuskovic, who is unlikely to be rushed into first-team contention and may instead go out on loan.

Spurs have been linked with a move for Bournemouth's Antoine Semenyo and it would be no surprise if they are targeting a goalscoring winger given Son Heung-min's decline in form and the relative inexperience of Wilson Odobert.

Reinforcements may also be required in the centre of the pitch, with both Rodrigo Bentancur and Yves Bissouma entering the final year of their contracts, although Frank is reportedly a long-term admirer of Archie Gray and could look to utilise the youngster in midfield.

The 19-year-old mainly featured as a makeshift defender in his first year at Spurs but sees his future further forward.
