19-year-old Zouma joined the Blues from St. Etienne in a £12 million deal back in January, remaining in Ligue 1 until the end of the season as part of the agreement to eventually take him to Stamford Bridge.
With Gary Cahill and John Terry impressing as Jose Mourinho's first-choice centre-back pairing throughout the 2013/14 campaign, many expected Zouma to be sent out on loan once again this term, but ultimately he has stayed in West London with David Luiz's eye-watering £50 million move to Paris Saint-Germain leaving Chelsea somewhat short of cover at centre-back.
Premier Leauge 'monsters'
Unsurprisingly, Zouma - pre-season friendlies aside - has yet to make a single appearance for the club, although Sanogo has given him a helpful hint as to how he may cope with the demands of the Premier League in the event that he is called upon by Mourinho to step into the breach.
"I told him he needs to get in shape because the Premier League is demanding from a physical point of view. There are some monsters [in the league]," the Gunners frontman told the French media in an interview that was brought to our attention by the Daily Express.
Although he clearly believes that his friend needs to bulk up a little, Sanogo was also quick to suggest that it will not be too long before Zouma proves himself worthy of a regular starting berth at Chelsea.
"But Kurt, he's a beautiful player. It will happen for him," he continued. I don't think he'll spend very long on the bench."
Sanogo out, Welbeck in?
While Zouma remains confined to the sidelines, Sanogo - who has scored three goals for the France U21 side during the recent international break, including a brace in a 5-1 rout of Kazakhstan and a well-taken volley in Monday night's hard-fought draw with Iceland - has made two starts so far this season for Arsenal.
After leading the line for the narrow opening day victory over Crystal Palace at the Emirates Stadium, the former Auxerre youngster also reprised his role for the trip to Leicester with Olivier Giroud unavailable for selection with a foot injury that is expected to keep him out of action until the new year.
Despite being given the opportunity to impress, however, many Arsenal fans have become visibly impatient with Sanogo and the deadline day capture of England forward Danny Welbeck from rivals Manchester United is likely to see his playing time under Arsene Wenger curtailed somewhat moving forward.
