When you translate the tweet on twitter it says
"Colombia and Scotland Press FB, the G. Rangers shirt wearing a 21-year-old Colombian striker Alfredo Morelos wrote that he was seriously interested. With the right wing and left flank, Morelos played 14 goals and 4 assists in 31 appearances this season."
I think he just likes searching for an retweeting videos of himself.
He has made no secret since he joined that he wants a move to the EPL or a similar league. He is very motivated so if we don't get the right offer in he'll keep trying his hardest til a club in those leagues bring in the right offer.
