The English midfielder has tallied 13 goals and 11 assists in 41 games this term, including a strike in our seven-goal Champions League thriller against Real Madrid.
“He's been amazing,” KDB hailed. “I have seen him from a little boy with massive potential.
“Whenever you come up to the first team, you are a little bit shy. It takes time and playing time to get comfortable.
“In the last two years, he has been very comfortable and you see the difference in the way he plays. He doesn't play with ups and downs – he does what he needs for this team.
“He isn't a young talent anymore – he is one of the guys now. It’s a big step to make but everyone looks to him to make a difference because he can.
“He has proven he can do that loads of times and he will do more times in the future. I’m hoping he can do the same in the future.”
