Higuain is on the brink of signing for Arsenal in a club record deal.
"I would love it. Higuain is a part of football, and I always loved how he played for Real Madrid. He is a scorer and would be a reinforcement that we could really use," Monreal told Marca.
"Arsenal are one of the biggest teams in England and this summer they are working towards good signings to break that [trophy-less] streak."
