The Premier League quartet have all been put on high alert after learning that Real Madrid are planning to re-sign the forward from Serie A giants Juventus this summer, although the La Liga outfit will look to offload him to the highest bidder during the forthcoming transfer window.
The 23-year-old, who has eight international caps for his country and is set to be included in Spain’s EURO 2016 squad later this year in France, has scored 11 goals and provided a further 11 assists in 45 appearances in all competitions for Juve this season.
Morata, who left the Bernabeu for Turin back in July 2014, is set to return to Madrid when they exercise a £23.6m buy-back option in his current contract.
The report then suggests that Zinedine Zidane’s side will be willing to then part with the forward for £40m – with United, Arsenal, Chelsea and Liverpool set for a four-way battle for his signature.
Ligue 1 champions Paris Saint-Germain have also been named as fellow potential suitors.
