Chelsea needs to offer €120m for Inter Milan striker Romelu Lukaku.
The Blues have their €100m rejected for the Belgian international who is not seeking an exit this summer.
Inter would accept €120m for the star striker as the club needs to raise funds having been hit hard financially by the coronavirus pandemic.
Lukaku scored 24 goals and made 11 assists in Serie A last season and secured the league title.
The 28-year old striker is not expected to force a move out of San Siro this summer as he is enjoying his time at the Italian club.
“I did get to relax, but I’ve also been training to stay fit and be able to start [the season] well,” Lukaku told the club’s official media channel.
“We now have a few weeks to prepare as well as we can for the new campaign. We hope to do well and achieve even more than last year.
“I’m thrilled to be back. We hope to continue down the path that we’ve started and to keep winning. All the players will work hard to make your dreams come true.”
