Manchester United, Real Madrid and Barcelona have all done to sign Skriniar, who continues to impress for Inter Milano in San Siro.
The need for the Red Devils, however, is undoubtedly greater with Jose Mourinho still bewildered by the team's failure to land a center-back in the summer.
Manchester United saw an attempt to defeat Harry Maggir, while Toby Adebayard, Diego Goetin and Jerome Boehten were all in Tottenham, Atletico Madrid and Bayern Munich respectively.
The Red Devils have so far had something to do with what they have.
Victor Lindelof is finally developing, but Chris Smalling, Phil Jones, Eric Bailly and Marcos Rojo remain irregular.
According to recent reports, United would like to sign Skriniar from Inter when the shuttle window opens again in January.
Real Madrid and Barcelona are also associated with the player.
But Inter boss Spalletti suggested that the Spanish clubs would have to pay a PREMIUM to sign a player estimated at £ 89m.
Speaking after a 1-1 draw with Barcelona, Spalletti said: "How much does Skriniar cost? 100 Million Euros.
"If I was Barca, I would pay 120 million and I say that 20 million euros is the advice.
"If I was Real Madrid, I would give 140 million euros, including a margin of € 40 million."
However, negotiations with Inter could be difficult.
In the summer of 2017, United came calling Ivan Perisic.
However, Croatian international remained in place after the Red Devils failed to reach the £ 50million asking price.
Inter is also interested in Anthony Martial.
Martial was in good shape for United recently, scoring five goals from its last five away games.
The International Convention of France in Old Trafford expires in 2019, although the club will activate a one-year extension.
But Inter wants to break him and ask him in any Skriniar talks.
