The French midfielder has been linked with a big money move to Stamford Bridge all summer, with the Blues rumoured to be the sole frontrunners in this transfer race all along.
The alternatives to Matic would be Sevilla's Steven N'Zonzi or Matias Vecino of Fiorentina, who can go for €24m before August 10.
He was also influential in the Champions League and helped the team reach the last four of the competition.
To give that some context, N'Golo Kane received a rating of 7.23 in the Premier League last season, while Tottenham's midfield enforcer Victor Wanyama managed a rating of 7.21.
Chelsea have reportedly seen off competition from Manchester United in pursuit of Tiemoue Bakayoko and are set to complete the player's signing.
Morata has proven clinical at Juventus and Real Madrid, and Chelsea will have to shell out close to $90 million to sign him. Medical in next few days.
The rumours were that Manchester United would sign Chelsea's Nemanja Matic once the Bakayoko deal was completed, but following their move for Lukaku, Chelsea were believed to be unwilling to do business for the Serbian.
However, Manchester United look to have turned the tables with Bakayoko set to join compatriot Paul Pogba at Old Trafford. Arsenal began at £30 million for Lemar but Monaco will probably end up wanting above £45 million in a summer when it could lose many of its best players.
