Luis Suárez, Barcelona to Atlético Madrid (£5.5m)

The transfer story of the summer was a move that didn’t happen, but while Lionel Messi stayed at Barcelona, several high-profile teammates were ushered out. Ivan Rakitic, Arturo Vidal and Rafinha left for cut-price fees but the departure of Suárez caused the most anger – not least with Messi. “You did not deserve for them to throw you out like they did,” the Argentinian told his strike partner via Instagram.

Suárez has said the manner of his departure reduced him to tears, but it may be Barça who look back with regret. Having initially tried to dictate his destination, the club were forced to let Suárez join Atlético for a £5.5m fee made up entirely of variables. The Uruguayan may be nearly 34 but forcing out such a pivotal player was a big risk. Handing him to a title rival looks careless at best, and his explosive debut showed what he can do as part of an artful strike duo with Diego Costa.

Pierre-Emile Højbjerg, Southampton to Tottenham (£15m)

The Danish midfielder spent four years at St Mary’s but his departure caused little consternation among Southampton fans. Højbjerg impressed in spells but struggled for consistency, and was stripped of the captaincy in June after expressing his desire to leave. Having got his wish, Højbjerg has shown why José Mourinho was so keen to buy him. Nobody has completed more passes in the Premier League season, and the former Bayern academy product is building a solid midfield foundation with the improved Tanguy Ndombele. If he can maintain his strong start, £15m for a 25-year-old looks a steal.
