The Chelsea forward made 34 appearances across all competitions for the Championship club, including 25 starts.
At Stamford Bridge, Boga operated primarily as a forward. But speaking to Goal, the 21-year-old revealed he now has experience playing on the wing.
"I played in all different positions. With Redknapp, at the beginning, everyone was happy because I was playing as a number 10," said Boga. "I was high up the pitch and working in a second striker position, where I played throughout my Chelsea youth. So for me, that was important.
"I can also play on the wing and did that a lot this season. I can also play as a striker. I have learned to play as a striker. I think it helped me survive, especially this season, because if I could only play as a number 10 then I think I wouldn't have lasted long in this team with their problems."
