Cristiano Ronaldo amid the forward informing Manchester United he wants to leave the club this summer if a suitable offer arrives.
Manchester United currently insist Ronaldo is not for sale and have reiterated that he is contracted until 2023.
But the 37-year-old has made clear his desire to depart and did not return for pre-season training on Monday as scheduled, citing family reasons.
Reports in The Athletic earlier this month suggested the Blues are weighing up the idea of signing Ronaldo.
Tuchel is in need of a new centre-forward at Chelsea this summer after £97.5million club-record buy Romelu Lukaku, who scored just eight Premier League goals in 2021/22, was allowed to rejoin Inter Milan on loan.
Ronaldo bagged 24 goals for a United side in disarray last season, meaning on paper he appears to be exactly what the Blues are missing at the pinpoint of their attack.
Yet Tuchel is concerned the former Real Madrid and Juventus forward’s presence would disrupt his plans for a flexible and fluid frontline similar to Jurgen Klopp’s great Liverpool side that won the Champions League in 2019.
In a video posted to social media, A coy Thomas Tuchel laughed before saying ‘I will not tell you’ when asked by a fan if Chelsea will sign Cristiano Ronaldo this summer.
