Arsenal are preparing to announce the £52 million club-record signing of Alexandre Lacazette following a successful medical and have also told Hector Bellerin that he cannot leave this summer.

Lacazette spent the day at the club’s London Colney training base where he met his new team-mates and finalised a move to the Premier League ahead of a pre-season tour next week to Australia and China.

It is Arsenal’s second signing of the summer following the arrival of left wing-back Saed Kolasinac but further ins will now be shaped by likely departures elsewhere through the squad.

Bellerin is a target of Barcelona and it is understood that he has discussed his situation this week with manager Arsene Wenger, who has made it clear that the 22-year-old will not be sold just months after agreeing a new contract that lasts until 2023.
