Ferencvaros coach Stanislav Cherchesov says Arsen Zakharyan must think carefully about moving to Chelsea.
The Dynamo Moscow winger remains a target for the Blues ahead of the January market.
Cherchesov told Sport-Express: "I coached Zakharyan for a couple of days and before that I closely followed him. At the age of 17, not everyone is taken to the national team. We called him because we saw the level. It is a pity that he fell ill and could not continue to work with the team before the Euros.
"The main thing is that moving to Europe should not be a jump, not a leap, but a natural step forward. There is a plus in the current situation: these six months, if you know for sure that you are moving, you can learn the language, psychologically prepare for what awaits you, in order to go already with a certain basis.
"Dynamo is the country's top club, but Chelsea is on a completely different level. And there is another life. You have to be ready for all this."
