“I did talk with him on the phone as soon as it came out that he was positive,” Mateo Kovacic told reporters. “I was very sad about that because he is doing excellently and he is my teammate.”
“I don’t give him too much advice but we do talk a lot. I have seen Billy’s abilities from the first time he started training with the first team.
“He can become a really excellent player so it is up to him to work hard and to get better with each day. I am sure that, with his personality, he is going to do that.
“Billy’s qualities cannot be brought into question. He is still a young player but he has played a lot of good matches for Chelsea and for his national team.
“He is definitely going to be an important player for Chelsea in the near future.”
Due to the positive Covid-19 test, Billy Gilmour was unable to contribute as Croatia beat Scotland 3-1 to knock them out of the Euros.
Despite being heavily linked with a loan move away this season, Billy Gilmour is clearly highly rated at Chelsea and a concrete part of any future plans.
