While confirmation of the deal was met with a level of benevolence from both sides, Conte has confirmed there will be no ill-will from him towards a frontman who netted 58 goals in 120 appearances in west London.
"Last season Eden played a really important season, played very well and he was very important for us in winning the league", the Italian told a news conference on Tuesday.
Despite having won just one of its three league home games, Chelsea has been perfect on the road and stays within three points of the Manchester sides at the top of the table.
He expressed his gratitude to Atletico for making the move, which will be officially registered on January 1, 2018.
Conte who won the UEFA Champions League with Juventus in 1996, said the duo of Pedro Rodriguez and David Luiz should be available. The international forward signed his new contract after successfully passing the medical tests that he underwent in two phases: last Saturday and Monday.
Speaking to France Football magazine, Hazard said: "You don't need that (tracking back to help out the defence)".
In January, Atletico fans will be able to enjoy the sight of returning hero Diego Costa lining up with shining star Griezmann in attack, and the potential of their silk and steel partnership will make Diego Simeone's men a force to be very much feared in the latter stages of the competition.
He added: "I understood him myself perfectly". Maybe they deserved to win the game.
"The team is in a very good moment, physically and mentally", Filipe Luis said.
Belgian midfielder Eden Hazard is yet to start in the Premier League this season after recovering from a broken ankle he suffered in June. "No wonder so many big clubs are prepared to pay silly money for him".
The Spain international will wear the No 18 shirt at the Wanda Metropolitano outfit.
Costa had been back in Madrid since last week and was pictured in the crowd during Atletico's match over the weekend.
Antonio Conte will have a full strength squad to select from with the exception of Danny Drinkwater, who continues to recover from injury. He is not only the Diego that is seen on the field.
"It is of course good for Diego but also for Atletico and Chelsea as well".
