Chelsea have bargain Alexander Isak backup already identified after £115m enquiry

Chelsea have a long list of striker targets this summer and have already made several approaches to clubs.

Enquiring with Newcastle United about Alexander Isak is reportedly the latest of these. It would also be the most expensive move, with the Premier League rivals expected to demand a record-breaking fee to part with the Sweden international.

Talks have also happened with Atletico Madrid, Aston Villa, Hoffenheim and Lille about Samu Omorodion, Jhon Duran, Maximilian Beier and Jonathan David. Isak and Newcastle are now another to add, but the club's list of centre-forward targets seemingly extends even further than just that.

The Daily Mail claims Dominic Calvert-Lewin is another name featuring further down the list for Chelsea. Everton have offered the former England international a new contract, but the player has yet to renew and thus will become a free agent next summer if no extension is agreed.

Therefore, the 27-year-old could be available for a cut-price fee should the Merseyside club sell this summer rather than lose their talisman for nothing in 12 months. Chelsea have reportedly been monitoring the situation since earlier this month. Newcastle, of all clubs, were linked with signing Calvert-Lewin last week.

Talks, however, are now believed to have ended as Everton are said to be holding out for £40 million. That is seemingly too costly for Newcastle and could prove the case for Chelsea should they formalise any interest in the striker.

It is possible, though, that the approaching accounting deadline around complying with the Premier League's Profit and Sustainability rules this upcoming season could see their price tag plummet. Everton have fallen foul of PSR rules for the last two seasons, and selling Calvert-Lewin would allow the club to book a significant profit on the £1.5 million they signed the striker from Sheffield United for.
