Sterling, who saw Manchester City’s 8-0 demolition of Watford from the bench, has long been on the radar of Los Blancos who are still looking for a long-term replacement of Cristiano Ronaldo.
The 24-year-old has seen his career move on an upward trajectory since leaving Liverpool for Manchester City in 2015 for a hefty transfer fee of £49m.
With the arrival of Pep Guardiola as City manager in 2016, the English forward has emerged as one of the best wingers in the world. He was a pivotal part of the City squad that won back to back Premier League titles in the last two seasons.
Sterling’s form in the new season has allowed some to compare him with the likes of Lionel Messi and Cristiano Ronaldo as the former Liverpool man has already managed 4 goals in his first five appearances this campaign.
