Arsenal manager Arsene Wenger has revealed exactly what it was that made him sit up and take notice of Alexis Sanchez - the player's endless energy.

Speaking to, Wenger recalled the time he first saw Sanchez in action, playing for Udinese several years before Sanchez actually joined the Gunners. What he saw clearly stuck with the Frenchman.

"He was very dynamic, very direct and very straight to the point," he explained.

"He was one of these players where his energy and the intensity of his energy level hits you straight in the face. It is strange because he catches your eye with his energy and level of commitment he puts into everything he does and that is what remained with me."

Sanchez eventually arrived in North London in 2014, by way of a trophy laden spell at Barcelona, and took the English football by storm.

The Chilean has had a somewhat disrupted second year after his involvement in the Copa America over summer and a more recent period on the sidelines through injury. He made his return to action against Chelsea, though, and will be vital if the Gunners are to end a 14-year title drought.

Another player who will have a huge role to play over the next four months is Olivier Giroud, who was devastated to be sacrificed on Sunday when Per Mertesacker's red card forced a tactical reshuffle.

For Giroud, a surprise French champion with Montpellier in 2011/12, his long, tough road to the top is what he says has made him and given him the hunger to succeed.

"When you have to face difficulties it always helps you in the future when you have to be strong and have to face your responsibilities," the striker told

"It definitely helped me in my career and that's why I can say that I am tougher today. I don't want to stop here and I always want more because when all this stops I don't want to regret anything. I really want to give everything to my limit."
