The young forward who made headlines last week by scoring on his first start for the Spanish national team - in a 5-1 Euro 2016 qualifying win over Macedonia, in Valencia - is reportedly close to putting pen-to-paper on a contract extension.
This is according to Spanish newspaper AS - brought to our attention by the Daily Star - who claim that the hierarchy at the Mestalla have made tying Alcacer down to a long-term deal their main priority.
Valencia to increase Alcacer's release clause to £40m
Valencia, who hope to secure a return to the Champions League via a top-four finish in La Liga this season, plan to increase the striker’s release clause to £40 million - making it incredibly difficult for Arsenal, Chelsea, or any other interest club to secure his services in the near future.
Los Che appear to be acting swiftly following reports claiming that Arsenal were preparing to submit a formal offer when the transfer window re-opens in January.
Gunners’ boss Arsene Wenger wants to bolster his attacking options, despite the £16 million acquisition of England international Danny Welbeck from Manchester United earlier this month, and had identified Alcacer as a realistic option.
Chelsea and others have sent scouts
Chelsea, Barcelona and Real Madrid are also known to have sent scouts to run the rule over the Spanish striker in recent weeks - and Jose Mourinho, Luis Enrique and Carlo Ancelotti have all received positive feedback.
Alcacer scored 14 goals in 37 appearances for Valencia last season, following the departure of Roberto Soldado to Tottenham, and has already netted two goals in three games at the start of the 2014/15 campaign.
Will Alcacer delay signing the new deal?
However, the talented youngster might have some reservations about committing his long-term future to Valencia after the Spanish club signed Alvaro Negredo from Manchester City at the end of the transfer window.
Alcacer has flourished while playing as Valencia’s lone striker, but his position will inevitably come under threat when Negredo returns to full fitness in a few weeks’ time.
Valencia head coach Nuno Espírito Santo and president Peter Lim will attempt to convince Alcacer that the best place for him to continue his development is at the Mestalla, but his agent may persuade him to hold tight on signing that new deal until Negredo returns from his lengthy lay-off.
