United and Liverpool share a bitter rivalry and Coutinho, who spent five years at Anfield between 2013 and 2018 before sealing a lucrative move to Catalonia, knows he will receive a hostile reception from the Old Trafford faithful.
“If they boo myself and Luis Suarez, then that’s normal at Old Trafford because of the team we used to play for, but it won’t make any difference to me,” he told the Spanish media.
“And, even more than that, it is an incentive to play better and to be even more focused.
“I know that games against Manchester United are special. I learned what they meant during my time at Liverpool when we lived it so intensely with the fans.
“I have that nailed in my memory and, even though this is a different stage, if Barcelona knock United out of Europe, it will be a double personal satisfaction for me.”
