After being subjected to racist abuse twice in 11 days, Chelsea have offered counselling to their teenage winger Callum Hudson-Odoi
Chelsea reported that Hudson-Odoi, 18, heard monkey chants during their Europa League win at Dynamo Kiev on March 14, which UEFA is now investigating.
The teenager was also one of several England players abused during the 5-1 win over Montenegro on Monday.
After the Montenegro win, which was Hudson-Odoi's full England debut, the winger described the abuse which also targeting Danny Rose and Raheem Sterling as "unacceptable".
The youngster is understood to be faring well since then, but will be offered a range of support if he needs it.
UEFA said "disciplinary proceedings" had been opened against Montenegro with one charge for "racist behaviour".
Hudson-Odoi said after the Euro 2020 qualifier: "When you are hearing stuff like that from the fans, it is not right and it is unacceptable. Hopefully UEFA will deal with it properly.
"When me and Rosey went over there, they were saying 'ooh aa aa' monkey stuff -- we just have to keep our heads and keep a strong mentality."
England boss Gareth Southgate said: "We have to make sure our players feel supported, they know the dressing room is there and we as a group of staff are there for them."
Chelsea are next in action at Cardiff City on Sunday as the Premier League returns after the international break.
