Negotiations between the Red Devils and the Spanish forward have reportedly started for a potential transfer fee of around £25 million (€30 million), according to a recent tweet by the Spanish journalist Pedro Morata of Cope.

The legendary Karim Benzema and Celta de Vigo's Iago Aspas scored more goals in La Liga than the 27-year-old Spaniard, who established himself as Espanyol's leading scorer.

The forward, who has spent the last two seasons as the team's leading scorer, has excelled during his two-year loan with Vallecano.

The prolific striker has managed to net an outstanding 45 goals and six assists in 89 appearances for the Spanish club.

Eric ten Hag has a tough season ahead of him, with the newly appointed Red Devil manager already off to an embarrassing start following two back-to-back defeats.

The Red Devils’ first defeat was against Brighton and Hove Albion at Old Trafford, where the 20-time-league winners lost 2-1, with the only United goal an own goal by Brighton’s Alexis MacAllister.

The embarrassment didn’t stop there, though, as ten Hag’s squad was thrashed 4-0 by Brentford at the Brentford Community Stadium.

With United failing to score a single goal for themselves, it’s not surprising that the Manchester club are on the lookout for a new forward this summer.

However, the Red Devils will need to move swiftly if they wish to sign additional players as the window closes in a couple of weeks.
