This is according to The Athletic who have claimed that a deal for the Borussia Dortmund striker looks a long way off as it currently stands.
Kalajdzic, 24, had an impressive Euro 2020 campaign with Austria and as result, the German club have put a £34million price tag on the striker.
The 6ft 7 striker will offer physical presence up top- something they have now lost with Olivier Giroud moving away from the club this summer for AC Milan.
The 24-year-old joined the club 18 months ago and hit 17 goals in his first full season in the Bundesliga, which has alerted the west Londoners.
The head coach of the Austrian National team Franco Foda has raved in the past about Kalajdzic’s qualities within the penalty box, and he believes that he could be a real asset for any team he joins in the future.
“He has developed extremely in the last few weeks and months and has taken the momentum with him. In the beginning, you have always noticed what qualities he has, but now he has also been ripped off in front of goal, where a striker has to be.”
“He has good anticipation in the penalty area. It was no coincidence that he scored these goals. We are obviously delighted that we now have more alternatives and a striker who scores. It’s all the better for a coach, when he is spoiled for choice,” he added.
It is known that Premier League opposition could rival the Blues for the tall striker’s signature, with West Ham and Liverpool reportedly eyeing a move.
The second option for the Stamford Bridge club as stated by The Athletic is ex-Liverpool striker and now Southampton forward Danny Ings.
Ings only has 12 months to run on his current contract on the south coast, and the 28-year-old has shown no signs of committing his long-term future to the Saints, with Tottenham and the Blues keeping a close eye on developments there.
Ideally, Roman Abramovich and co aren’t wanting to think of alternatives, as they are so set on acquiring £150m Haaland this summer.
But the lack of movement on the deal is worrying, especially with the 2021/22 season just around the corner.
The latest on the deal is that the Blues hierarchy are preparing a ‘fantasy’ offer to test the resolve of the German club, who remain adamant that the 20-year-old is not for sale.
Sky Sports’ update a week ago still remains up to date on where the deal is at when it comes to the current state of play.
“It’s going to be very difficult,” Kaveh Solhekol told Sky Sports News. “It’s no secret that Chelsea want to sign a number nine this summer. And Erling Haaland is their number one target.
He went on to add: “As far as Haaland is concerned, Borussia Dortmund are saying he is not for sale, even though he has this release clause in his contract which means he could leave next summer for about £75m.

“Now some of the biggest clubs like Chelsea are thinking that they could steal a march on their rivals this summer by offering Dortmund more than that release clause. Maybe that will tempt Dortmund to sell him.
“But of course, Borussia Dortmund are saying he’s not for sale, and once more we’ve already raised £73m by agreeing to sell Jadon Sancho to Manchester United. But still Chelsea are interested and still want to sign him.
“We’ve spoken to someone who’s involved in the deal, and he said it’s going to be very difficult. He said at the moment, it looks like ‘mission impossible’ but Chelsea are trying. It’s unlikely but who knows, it could still happen.
If the Chelsea hierarchy aren’t to secure the signing of the 40 goal-a-season forward this summer, Foda has already given his seal of approval for Kalajdzic to be one of the main men to lead Tuchel’s title-challenging side next season.
