Newcastle is interested in signing RB Leipzig striker Benjamin Sesko when Alexander Isak leaves the club.
Isak has informed Newcastle that he wants to explore his options this transfer window.
Newcastle has investigated the conditions of a deal for Sesko, who was a target for Arsenal before they decided to pursue Viktor Gyokeres.
Sky Sports News understands that the Sesko camp previously rejected a proposal from a Saudi Pro League club. Newcastle has been interested in Sesko since last summer.
Newcastle had rejected an offer for Brentford Striker Yoane Wissa, but it is clear that he was prepared as a second choice for Isak.
So far, there has been no official or formal transfer request from Isak, and although there have been talks about a new contract in Newcastle in recent months, nothing has been agreed at this stage.
Isak has left for three years to walk his current deal, so Newcastle is in a strong negotiating position and appreciates the player at £ 150 million, while he insists that he is not for sale.
The Sweden striker was sent home by Newcastle manager Eddie Howe prior to the 4-0 defeat for the season for Celtic last weekend because they are influenced by transfer speculation after an approach from Liverpool.
Isak was not part of the traveling party to Singapore on Thursday, where Newcastle said he had been left at home due to a small thigh problem and a long -distance flight would not have helped his recovery. But the speculation is a contributing factor that is lagging Isak in Newcastle.
Liverpool held an informal approach for Isak last week before he signed Hugo Ekitike – and it is assumed that they remain huge admirers of Isak. In the meantime, Chelsea is not in the race to sign Isak.
The blues have full faith in the strikers they have in their team for the Premier League and Champions League next season.
What did Newcastle -Baas Howe say about Isak last week?
Newcastle boss Eddie Howe spoke after Alexander Isak was sent home from the team prior to the 4-0 defeat against Celtic last Saturday:
“It was my decision. He traveled with us to Glasgow, but I decided to send him home because of the speculation around him.
“The last thing he wanted is to look in the stands, that was not fair for him. But I am convinced that he will be a Newcastle player who comes the end of the window.
“We have some of those players who are irreplaceable. Your top players are so hard to find, so hard to recruit and so hard to develop.
“So if you have them, you have to cherish them. Of course we are desperate to keep it as part of our team.
“I have had discussions with him, but that is not abnormal. I respect the career of a player and how short it is. Alex has been really good, he is really well trained and I realize that there will be noise around him.”
Does Newcastle still want Wissa?
Further conversations will take place on Thursday in Brentford about the future of Wissa in the midst of the interest of Newcastle.
The player wants to go, but Brentford does not want to sell him after they have sold Bryan Mbeumo to Manchester United for £ 71 million.
Brentford's appreciation of Wissa has increased after the sale of Mbeumo because it is seen as a risk of losing both players.
The couple scored 39 goals between them in the Premier League last season.
Sky Sports News has been told that Brentford Wissa appreciates no less than £ 40 million.
Newcastle, who are increasingly hopeful that they can get him for about £ 35 million, does not want to pay too much for a player they are currently seeing as a number two striker for Isak.
Analysis: What is the next step for Isak in Newcastle?
Sky Sports News' Keith Downie:
“Newcastle wanted to use this window to build; they wanted to bring in four players. A keeper, a central defender, a right -wing wing player and another forward.
“They brought in Anthony Elanga, they wanted to enter a second striker and compete with Alexander Isak. They had those conversations with Frankfurt [about Hugo Ekitike]Liverpool hijacked that and still preserves an interest in Isak.
“It is not what the Newcastle fans want to hear prior to a Champions League season where they fight on two large fronts. They want to hold their best players -the last thing they want to hear is that the head of Isak is being played.
“Eddie Howe is a great man manager, but he will have to do the best man management task of all time to try to get Isak in a positive state of mind that goes into the season.
“Reading between the lines, the fact that he was asked to explore his options, his head has been turned. He was left here in Newcastle, one because of the injury, but also because he was struck by interest.
“Isak is one of the best players in the Premier League, he is perhaps the best striker in the Premier League. He thinks he should be paid in this way comparable to the top strikers, and he is not in Newcastle. If he moved to a new club, whether it is Liverpool or elsewhere, he would be targeted in that way.
“The club will have to come to a kind of conclusion here – does he get a wage increase? Let him speak to other clubs? Or do they allow time and space that the situation can calm down in the coming weeks?
“But you ask me what is happening now, whether someone is coming in and the £ 150 million Newcastle is looking for, or Isak draws a new contract or bigger money, or he just gets his head back to a Newcastle player – and starts the season in a positive state of mind.
“But it's a delicate situation, this one. The last thing Eddie Howe wanted, the last thing Newcastle fans wanted. Howe sounded exhausted after the Celtic game on Saturday. There is currently no sports director, they are also looking for a new CEO.
“Eddie Howe and his cousin Andy were involved in the front of the entire transfer plan this summer and Newcastle were bruised. They tried for Liam Delap, Joao Pedro, Dean Huijsen and they couldn't get them.
“Newcastle is still in advanced negotiations about a deal for Yoane Wissa, but he was intended as the backup of Isak, not their only striker.”
