Unai Emery wants to create a “new history” with Arsenal as he prepares his side for Thursday’s Europa League semi-final first leg against Valencia.
The contest pits the Spanish boss, 47, against his former club, who he led to Champions League qualification on three consecutive occasions.
“Now it’s the Europa League, it’s both a way to win a title and also a path into the Champions League,” he said.
“We want to treat this semi-final like something important.”
He added: “We need our supporters and we need to create a big atmosphere – we are very excited and with big enthusiasm for the match.
“We are looking forward to playing, to being with our supporters, to doing the first leg’s 90 minutes with a big performance and with a good result. But we know it’s going to be very difficult also. I think we need [it] all. We need the players, we need spirit, we need energy, we need our supporters.”
