Unai Emery will go head to head with Nuno Espirito Santo once again when Wolves visit Emirates Stadium on Sunday.
The two have faced each other twice before, in La Liga when our head coach was in charge of Sevilla and his Portuguese opponent was Valencia manager.
So what does Emery think of his opposite number?
“He’s a good coach with experience,” he said. “Every coach from Portugal, in my experience, is very competitive and they are very organised coaches.
“They have discipline but also talented players, like at Wolves. I know that each match here is very difficult and we need to prepare so that we can continue to get better to produce a big performance every day.
“It’s about thinking of the next match after finishing the game in the Europa League. Then what’s very important is the Premier League and to complete our process and our progress to be in the best position.”
