The Hammers are understood to have an initial £31m offer for the France international rejected recently as they search for a marquee striker to lead their summer recruitment drive.
Such a sum would have made Lacazette the Londoners’ all-time most expensive player – a record held by Andy Carroll, who joined from Liverpool for around £15m in 2014 – and with such a vast amount of time to conclude deals remaining the Hammers are expected to push once again for him.
But, their hopes look to have been significantly dented, with reports claiming PSG have identified the Ligue 1 hot-shot as a candidate to fill the void left by the departing Zlatan Ibrahimovic.
It’s thought that the Parisians are willing to pay as much as £40m to take the striker from their divisional rivals, which would not only strengthen their first-team ranks, but significantly weaken one of their direct competitors in the French top tier.
Lacazette netted 23 goals in 44 appearances through 2015/16, but has been left out of Les Bleus’ EURO 2016 plans.
