The Uruguayan struck the winner in the second half after both teams had been reduced to 10 men. Ansu Fati was sent off for Barca, while Pol Lozano followed shortly afterwards.
Suarez’s goal takes him into third place in the list of all-time Barcelona goalscorers, moving past László Kubala, and offered his response to hitting the landmark after the match.
“I just feel privileged to be able to enjoy playing for the best team in the world,” he said.
“We knew it was going to be difficult and we knew their situation. We didn’t create chances in the first half because they were very organised. They made it difficult for Semedo and Alba to push up on the flanks but eventually the chance came and I was delighted to take it.
“The manager takes the decisions. He wanted to find a formula and this is the one he’s trying at the moment. It’s the first year for Antoine here, we know it’s difficult the adaptation period, but the other day we all enjoyed a brilliant performance from Griezmann.
“What we have to do is win our next three games, whatever Madrid do is up to them. If they drop points fantastic, we have to think about being there if they do.”
