The 26-year-old, is in Spain at Euro 2020, excelled for Atletico during the 2020-21 campaign, scoring 13 times and contributing 12 assists in 45 appearances in all competitions.
The ex-Real Madrid ace - who won the 2018 Champions League with Los Blancos - has chipped in with 13 goals and 12 assists in 43 games in all competitions this term.
Manchester United are allegedly keen on the midfielder, with a report earlier this year claiming that the English giants were prepared to pay £68.5m for his signature this summer.
Atletico will issue a hands-off warning and have no intention of listening to any offers for their key man.
They add the only way United have a chance of landing his signature is by forking out his whopping buy-out clause.
Atletico for their part is in no mood to sell. They are in fact keen to extend the Spaniard’s stay at the Wanda Metropolitano.
He also provides some defensive stability when Atletico are sitting back, and helps with overloads from opposition full-backs.
Manchester United do want to improve their squad, and if this report is true and they manage to persuade Llorente into signing for them, they would be so much closer to success.
Llorente has 13 goals and 12 assists for Atletico across all competitions this season. He’s honestly been an amazing asset for the Rojiblancos.
