This is the new Real Madrid retro icon shirt, a long sleeved creation from Adidas that is a throwback to the Madrid of yesteryear. The kit was officially unveiled earlier this month but went on sale today (September 24, 2019).
The shirt, as you can see below, is predominantly white, with gold and navy detailing. Striker Karim Benzema is here seen modelling the jersey in the pics below.
Los Blancos have had a tough start to the season under Zinedine Zidane and lost their Champions League opener 3-0 to PSG at Parc des Princes a few days ago.
