Anzhi Makhachkala trio Christopher Samba, Samuel Eto'o and Roberto Carlos will reportedly travel to visit Bolton Wanderers midfielder Fabrice Muamba in the coming days.
Former Blackburn Rovers defender Samba, a close friend of Muamba, revealed to Sky Sports News that he, along with his teammates, will seek permission from Anzhi boss Guus Hiddink to depart Russia.
Muamba suffered a cardiac arrest during Saturday's FA Cup tie with Tottenham Hotspur, and was later taken to hospital.
It has been revealed recently, however, that the 23-year-old is showing "small signs of improvement."
