Former Middlesbrough manager and Madrid coach Aitor Karanka has heaped praise on the 24-year-old, who struggled to earn a regular starting role last season in the Spanish capital.
Jose Mourinho’s former assistant at the Bernabeau knows Morata well and is in no doubt about his talent, report the Manchester Evening News.
Morata’s agent held fresh talks with the Spanish giants on Wednesday as United aim to make a breakthrough in their pursuit of the striker.
But Karanka has no doubt he would be a success if reunited with Mourinho at United.
He told Spanish radio station Cadena Ser : “Alvaro fits anywhere.
“We knew since he was with us at the age of 19 (his talent) and I know him since he was 17 because he came to the Under 17 World Cup in Nigeria.
“Alvaro is the classic player that can fit anywhere. He has everything.
“The year he spent at Juventus was good for him to mature. For this (Premier League) football he is a spectacular player.”
United want to tie up their move for the 24-year-old after securing their first summer signing in Victor Lindelof.
But Real’s valuation remains the biggest hurdle, with reports in Spain claiming the Champions League winners are holding out for £79m.
United’s executive vice chairman Ed Woodward is trying to negotiate a fee closer to £60m – but the deal hinges on Real’s resolve to hold out for their full asking price.
