This is at least in accordance with the comments of the representative of Skriniar.
In the summer, Manchester United tried to kill the upper center, but Jose Mourinho was rejected by not being able to sign Leicester's Harry Maguire or Tottenham star Toby Alderweireld and play with Edu Woodward, Executive Vice President.
Although the first team is instructed to run Viktor Lindelof regularly, Mourinho is still question mark over Chris Smalling and Phil Jones.
Barcelona and Real Madrid are also hunting for Skriniar, but the United must explore the possible deal 23 years old in January.
However, Skriniar's spokeswoman, Karol Csonto, insists that his client negotiates a new deal for San Siro, although his current contract ends in 2022.
"We're talking about that," said Csonto when asked about a possible extension of the contract, "Skriniar".
"We are working on it. This is the subject with which we will be more intensive in the coming months."
Csonto is also incredible Skriniar is happy with Inter, adding: "He is pleased with the Nerazzurri shirt, he is well in play, but he is aware that Serie A has some difficulties.
"Inter had won seven games in a row before losing to Atalanta. He's doing well. I'm happy.
"He is happy to play in the Champions League.
"Clearly, the goal is to grow with the team and improve on a daily basis."
Meanwhile, Inter boss Luciano Spalletti believes that Skriniar is worth £ 89million.
Last week he said: "How much does Scrinari pay for € 100 million?
"If I were Barca, I could pay 120 million euros and say that € 20 million is the end.
"If I were Real Madrid, I would give 140 million euros, including 40 million euros."
