Manchester United are threatening to gain the upper hand over Liverpool in the race for a player described as the 'Colombian Cristiano Ronaldo'.
Luis Diaz has been on the radar of a number of top clubs thanks to his goals for Porto and his breakout international tournament at last summer's Copa America.
The 25-year-old has been described as a "perfect" signing for Liverpool as they aim to address the precarious contract situation affecting their current forward line, but they're not alone in their pursuit of the player.
