Chelsea’s owner believes Grant could provide valuable assistance to Frank Lampard.
The Blues’ 3-1 defeat to Man City was their latest during a downturn in performances in the Premier League, Lampard and Grant reached the Champions League final together in 2008,
The Russian billionaire believes Grant’s experience could provide invaluable support to manager Lampard and his staff.
Chelsea have won only one of their last six Premier League matches and have dropped to ninth in the table.
Grant believes his strengths lie as a team manager rather than behind the scenes, so potentially the 65-year-old’s return to Stamford Bridge could be on a short-term basis.
“About the current situation, I can say only this. You need to be strong when things are not going well, when things are going well everyone is a genius and knows what to do,” Grant said in an Instagram post.
“But in the situation like this when things aren’t going well you need to be strong, look for solutions and show a lot about your character.
“What I can say to Frank and the others at the club is be patient, and more than this do whatever is necessary to do, that’s for sure. Two things: never lose it even when things are going well, don’t lose your fighting spirit at the highest level.
“And second, don’t lose what you have here [points at head] – you need to think right and look for solutions. If you do that, then everything will be OK because the quality is there and there is a potential like there was [at Chelsea] in my time.”
In 2018, the former Portsmouth and West Ham boss had a spell as manager of Indian Super League team NorthEast United.
Prior to that, Grant managed Ghana, leading them to the final of the Africa Cup of Nations in 2015, losing to Ivory Coast on penalties.
Grant guided Chelsea to the Champions League final in 2008 and Lampard scored 20 goals during 40 appearances in all competitions for the Blues during that season.
