Riga was nicknamed 'The Bullet' during his time with Levante as a result of his explosive pace, which helped him to score 28 times in 104 appearances in Spain, where he often played in midfield.
Riga said, "I hope to make this name 'Bullet' true, and I think I will."
"I hope so because for a football player it's very important to enjoy the fans and they can enjoy you."
