Tottenham Hotspur have opened talks with Ligue 1 club Lyon over a summer move for striker Alexandre Lacazette. Mauricio Pochettino is keen to bring in a backup for Harry Kane and has identified the Frenchman, with the clubs beginning talks over a proposed £30m ($43m) move.

According to the Mirror, Spurs chairman Daniel Levy is also keen on signing the striker. West Ham United and Paris Saint-Germain are also said to be interested in signing the striker, but the White Hart Lane outfit are said to be favourites to land the Lyon forward.

The Hammers, who are moving to the Olympic Stadium next season, are desperate to sign a top quality forward, but have seen their bid rejected by Lyon. Tottenham are hopeful of completing despite being unwilling to meet the French club's valuation of the striker. The Premier League side are said to be willing to pay just £24m, while Lacazette is valued at around £30m by his current employers.

Jean-Michel Aulas has given Spurs the green signal to make the signing, but has made it clear that they have to act fast. He has given interested clubs a deadline of 30 June if they want to sign key players from their team, as they will need to find replacements before the start of next season.

"If on 28th August, we are offered €80m for Alexandre Lacazette, he will not leave. However, if he comes to me in the days to come, because he has an offer he cannot refuse, it's possible," the Lyon chairman said, as quoted by the Mirror.

"Finally, if there must be departures, they will be before June 30. There will be none after, except for minor players," Aulas added.

Pochettino has made signing a striker a priority this summer in order to ease the burden on Harry Kane, who is the only recognised forward in the squad at the moment. The Mirror reports that the club are willing to sell Son Heung-Min after he failed to live up to expectations following his move from Bayer Leverkusen last summer.
