Chelsea and Manchester United have reportedly been given a valuation by Monaco for midfielder Aurelien Tchouameni.
The 21-year-old is said to have attracted widespread interest from Europe's top clubs thanks to his performances in Ligue 1 this campaign, with the two English giants reportedly at the front of the queue for his signature.
According to Tuttosport, Monaco have now informed interested parties that it would take an offer of at least £42m to capture the Frenchman.
Italian giants Juventus have also been linked with a January move for Tchouameni, although the report continues, saying that the Principality side are unlikely to part ways with the midfielder at the midway point of the campaign and are instead said to be open to discussing a deal for next summer.
The France international has featured in 12 of his side's 13 league games so far this season, alongside all four Europa League outings, taking his tally to 65 first-team appearances at the tender age of 21, while he now boasts five senior caps for Les Bleus, having played for the first time at the beginning of September.
