Bulgarian under-21 goalkeeper Nikolay Mihaylov was left speechless after completing his move to Liverpool yesterday.
Mihaylov joins on a three-year deal, with the option of a further two-year extension.
"I have no words. This is the greatest moment of my life," he said.
The 19-year old, whose father is president of the Bulgarian Football Union, was a member of the Levski squad that competed in last season's Champions League and has also represented his country at full level.
