Former Manchester United striker Diego Forlan isn't surprised they're tracking Atletico Madrid defender Diego Godin.
Godin is one of the names being considered by Louis van Gaal as he looks to add a world class centre back to his rear-guard this summer.
"My compatriot Diego Godin is one of the best defenders in the world, good enough to play for any team in any league," he wrote in his column for The National.
"In 2014, he had a better year than any other defender. He scored the goal in Camp Nou against Barcelona that won Atletico Madrid the league title on the final day.
"He scored in the UEFA Champions League final and very nearly won the European Cup.
"At the World Cup, he scored for Uruguay against Italy to take us into the knockout stages - with his neck.
"Was there a better central defensive partnership in club football than Godin and the Brazilian Miranda last season? Yet he was not named in the Fifa FIFPro World XI team of the year."
