According to talkSPORT, the London pair are both looking at the Belgian forward, ahead of a potential move in the January transfer window.
“There is not a single top 15 world club that is not interested in Batshuayi,” Marseille president Vincent Labrune told French source La Derniere Heure [as per talkSPORT].
“He is one of the most wanted players on the market. There were a lot of offers for him this summer, but he did not want to leave.
“He is proving himself on the pitch. And if clubs want him then they are going to have to pay up. Around €50m!”
The 22-year-old is one of Europe’s hottest young striker, having taken major strides in his game since moving to the French giants from Standard Liege in 2014.
Last season, he was regularly used from the bench—making only six starts and 19 substitute appearances—and scored seven goals.
There was a major exodus of players from the Stade Velodrome during the summer, with the likes of Andre Ayew, Dimitri Payet and Andre-Pierre Gignac all leaving the club. The exit in particular of Gignac has allowed Batshuayi to take the scoring mantle for OM.
He has scored eight times and contributed three assists so far this term, despite Marseille’s troubled start to the campaign.
The forward made his debut for Belgium earlier in the year, and would likely represent a better option for Chelsea than flop Radamel Falcao, who has scored only once since moving to the club from AS Monaco on loan during the summer.
Similarly, it remains to be seen how long Arsenal will be without Danny Welbeck, who is yet to play this term due to injury. If Arsene Wenger is serious about challenging for the title this season, Batshuayi could be the kind of explosive presence to give the Gunners the edge during the title run-in.
