Manchester City defender Benjamin Mendy is currently in Barcelona getting tests done on an injury sustained during Saturday's 5-0 win over Crystal Palace.
The 23-year-old full-back, signed for £52m from Monaco over the summer, begun his career in England in superb form.
Boasting an 100% record since being introduced to the first team, Manchester City have scored 18 and conceded just one goal in Mendy's four Premier League starts.
The attack-minded left-back could be set for an extended spell on the sidelines amid suggestions that he may have suffered a serious ACL injury.
Danilo, traditionally a right-back, is expected to fill in for Mendy in his absence.
Mendy has quickly earned a reputation in England as one of the "must-follows" on Twitter, constantly sharing hilarious banter with his new teammates.
Fellow City full-back Kyle Walker has upped his social media game to keep up with the former Monaco and Marseille star.
The French international had not tweeted since news of his injury spread but ended his silence with a brilliant tweet aimed at Duncan Castles.
Castles had claimed that Mendy could be sidelined for nine months - which appears to be more information than Mendy and the doctors who are assessing him currently have.
Pep Guardiola's Manchester City face a tricky trip to Stamford Bridge on Saturday when they face the current champions Chelsea.
Unbeaten in all competitions, the Citizens are top of the table and are considered the favourites to win the title this year.
Currently level on points with their Manchester rivals, Jose Mourinho's Manchester United are expected to be their main challenger.
The Red Devils are also in brilliant form and the Manchester derby at Old Trafford on December 9 is already being greatly anticipated in the north-west.
