Mikel Arteta, the Arsenal manager, told the club website: “Albert is a very intelligent player who has shown great maturity in his performances during his development.
“He has been coached well by Vincent Kompany and his team at Anderlecht. I know Vincent very well and he talks so highly about Albert and the positive impact he had to Anderlecht in recent seasons.
“We’re confident Albert’s ready for the next stage in his development and we’re looking forward to welcoming a new member to our squad with his quality and presence.”
