The 23-year old Bulgarian international is being heavily linked with a summer shift to Glasgow and says he would love to continue his career at Parkhead.
"They have a big history and their performance in Europe this year has shown they are ready to create new history.
"Last summer there were Italian teams interested and even though Serie A is one of the top leagues it's important for me I consistently play Champions League football. Celtic is somewhere I could achieve that.
"I just concentrate on playing. Hopefully a move can be organised this summer."
