The Ghana ace wrote for chelseafc.com: "Looking back to when I was a youngster coming through, I was on the road from the ages of 16 - 17 trialing at European clubs. I had two trials with Sir Alex at Manchester United when I was a kid before settling at Bastia. Hard work ensured I developed the skills I had and I was always looking to improve.
"Having played across Europe at a young age, I do believe this helped my development. This is why I think competitions such as last year's NextGen and the recently launched UEFA Youth League are great for the experience of young players."
