Ghana defender Baba Rahman is hoping to recapture the form that saw him once earmarked as a potential world's best left-back.
Rahman, who was signed by English giants Chelsea from German outfit Augsburg in 2015 following a superlative campaign, has struggled to live up to expectations since his major breakthrough.
The 24-year-old is currently on the books of Bundesliga side Schalke, where he is hoping to recapture his glory days.
"Never too late to become the best in the world," Baba tweeted on Sunday.
"It has not been the best of starts to the season but working every minute to turn things around quickly."
He has featured in all of Schalke's two successive defeats in the German Bundesliga.
