Philippe Coutinho can get "back to his best" if he seals a transfer to Chelsea this summer, according to Rivaldo, who admits that his fellow Brazilian has been unable to live up to expectations at Barcelona.
Coutinho emerged as one of the brightest young talents of his generation during a five-year spell at Liverpool, before opting to complete a big-money move to Spain in January 2018.
Barcelona snapped the 27-year-old up for £142 million ($176m) and tied him down to a five-year contract at Camp Nou, but his first full season at the club did not go according to plan.
