The Swedish international is highly rated around Europe and Antonio Conte wants him to strengthen Chelsea’s defensive options.
The 22 year old defender was a target for Manchester United as well, but Mourinho signing Eric Bailly earlier this summer has allowed Chelsea a clear run at the player now.
Earlier this summer, Manchester United submitted a bid for the player, but nothing came of it.
Now the Portuguese media are reporting that Chelsea are keen on signing the player without wasting any time and will therefore trigger his release clause (30 million Euros).
