Arsenal are close to spending their £50million summer transfer budget on Lucas Torreira, Bernd Leno and Sokratis Papastathopoulos.

The Gunners are closing in on the £26m signing of Sampdoria midfielder Torreira and they have approached Bayer Leverkusen over a £20m deal for German goalkeeper Leno.

Arsenal are expected to sign Borussia Dortmund defender Papastathopoulos for £16m and should all three deals go through then new head coach Unai Emery will be under pressure to sell players if he wants to bring more new arrivals in.

Emery has been told he has a restricted budget this summer and he will need to offload players to boost the funds available to him for transfers.

The Spaniard wants to rebuild the Arsenal squad for a top-four push next season and he will meet some players who are not at the World Cup this week to discuss their futures.

One of those players is Jack Wilshere, whose contract up at the end of this month.

Lucas Perez is expected to be told he can leave and Shkodran Mustafi could also be made available for transfer, with Arsenal’s head of recruitment Sven Mislintat having doubts over the defender.

Arsenal are discussing personal terms with representatives of Uruguay midfielder Torreira and a deal for the 22-year-old, who is in Russia for the World Cup, is close. Napoli are also interested in Torreira but Arsenal look to have won the race to sign him from Sampdoria.

Emery is also keen to sign a goalkeeper and Arsenal have made contact with Leverkusen over a move for Leno. The 26-year-old will replace Petr Cech as the Gunners No1.

Leno, who was left out of Germany’s World Cup squad, is keen to leave Leverkusen. Cech turned 36 last month and Emery has made a goalkeeper a priority this summer.

Arsenal are expected to complete the signing of 29-year-old defender Papastathopoulos on July 1.

Emery is also in the market for another central defender and the three new arrivals would leave Emery needing to trim his squad before he brings further new signings in.

The Gunners have already signed Swiss defender Stephan Lichtsteiner on a free transfer from Juventus.

Emery and Mislintat, together with chief executive Ivan Gazidis and head of football relations Raul Sanllehi, plan to reshape the Arsenal squad this summer in the post-Arsene Wenger era.
