Chelsea have a dismal recent record against City, having lost their last three encounters, if you include the summer's Community Shield.
However, Chelsea will not let Hazard go easily.
Yet, despite his fantastic from when he has played this season, Loftus-Cheek is yet to start a game in the Premier League so far in 2018-19 due to the fierce competition in the Blues' midfield.
Madrid could also seek to include Mateo Kovacic in the deal.
It is believed that Chelsea superstar Eden Hazard has agreed a huge transfer away from the Blues, amid reports he was recently offered a new bumper deal at Stamford Bridge.
However, Sarri said Chelsea's offer was on the table and now the ball lay in Hazard's court.
"The club is available to sign a new contract immediately but it's up to him if he wants to renew". I want Eden here, of course, but I want him here if he wants to stay.
"The deal is very hard for this reason, I think, because the club wants a short contract and the players want a long contract", he said.
Those comments would seem to be at odds with Chelsea's "unofficial" policy of only handing one-year contracts to players over 30.
However, reports in the United Kingdom say Chelsea's policy of only handing one-year contracts to players over 30 - Hazard reaches the milestone just over six months after his current agreement expires - could prove a stumbling block.
Chelsea FC will now turn their attentions towards their showdown with Premier League leaders Manchester City at Stamford Bridge on Saturday evening.
