Antonio Conte’s side are at the Camp Nou for their second group match, and the fixture will see Alexis return to the club where he spent three years.
The Chilean knows what to expect from his former team and is expecting a tough night back at the Camp Nou.
“At home they are very strong, They have the confidence to play there. If we have one chance or two chances, we cannot waste them,” he said.
“I played with United there and we wasted three or four clear chances. Then they have one or two, they get in, and you’re 3-0 down.
“If you want to beat Barcelona, you can’t miss any clear chances.”
