The authorities have decided to punish the attacker for exposing a text in which he thanks his family for their support during his long spell on the sidelines
The attacker broke his tibia during the Club World Cup last December, and celebrated his long-awaited return to competitive action by arriving as a second-half sub to score a superb goal in the rout of the Basque side.
After finding the net, the Asturian-born frontman removed his jersey to reveal the phrase 'Imposible Sin Vosotras' - 'Impossible without you', accompanied by a picture of his family.
The Spain international's emotional message has however infringed on RFEF statutes, which state that removing a jersey to display advertising or any slogan is considered an offence, and the 30-year-old has been punished accordingly.
The size of the fine has been set at between 2,000 and 3,000 Euros.
