The Dutchman was appointed last summer but this season has had its ups and downs; the Blaugrana could still complete the domestic double.

Koeman told reporters on Friday, in quotes that have been carried by Marca: “We have improved many things. I never think about my future if I win or lose a game.
“It’s a little bit strange that I need to answer questions like this because we had a run of 19 games without losing. We are losing one match and I need to talk about my future?
“Maybe I need to accept this. I have one more year of contract. I know it’s a big pressure and I can handle that but sometimes it’s a little bit strange.
“I accept this is part of my job, which is a huge honour.”
