Inter Milan are reportedly upset with Romelu Lukaku as the Chelsea forward is not responding to messages from his teammates and manager amid Juventus' interest.
This comes as the forward has been granted additional time away from Chelsea while other players have already reported back for pre-season.
According to Italian journalist Gianluca Di Marzio, Inter are 'annoyed by the attitiude of Lukaku, who isn't responding to the managers or his former teammates'.
In addition to this, the report states that Inter have become aware that there is 'an opening to Juventus', a team in which Lukaku previously said he would never play for out of respect for Inter.
