He will need no firing up the against the Champions League debutants from Azerbaijan.
Last season Cahill, along with his Chelsea team mates, had to watch the Champions League from the sofa after failing to qualify when they finished a woeful 10th the season before.
And if the Chelsea manager needs to make changes then he has Eden Hazard on the bench, along with new signings Danny Drinkwater and Davide Zappacosta. "If you asked me if we had a chance to win the title in England you'd have said zero", Conte said.
United has won three of its first four league games and has been more clinical this season, with new striker Romelu Lukaku scoring five goals in five matches in all competitions and midfielders Paul Pogba and Henrikh Mkhitaryan looking more risky going forward.
They will be hoping to keep the score down as low as possible and look to cause an upset when they play at home in the return fixture.
This is Antonio Conte's third Champions League campaign as manager. "It's a great competition and we must be pleased to be back after last season and proud to play in this competition and push ourselves". "In the Champions League we are starting a path and it will be very important to start building something important", he added. "I'm itching to play".
"We are at the beginning of a new era, and we must go step by step to reach the levels of Real Madrid, Bayern Munich and also Juventus".
"Our group rivals are very strong and experienced teams but it doesn't mean that we will surrender before the battle starts". However, the Blues turned it around in a hurry beating Tottenham Hotspur, their biggest title challengers last season, and the Everton decisively in games two and three.
It is nearly impossible to see the hosts losing this one, and I think it will be a rough start for Qarabag in their life in European football.
