Nicolas Otamendi suffered an embarrassing start to his career at Benfica after giving away two goals and a penalty during his debut.
The Argentinian joined the Portuguese outfit in a £13million deal after spending five years at Manchester City - where he picked up seven trophies.
However, fans were left somewhat unimpressed with the man who promised to help 'Benfica grow' after his dismal performance against Primeira Liga's bottom side Farense on Sunday.
Otamendi infuriated supporters by giving away a penalty for a foul on Serbian striker Nikola Stojiljkovic.
The 32-year-old was shown a yellow card for his challenge, but much to his delight midfielder Ryan Gauld missed his opportunity to convert from the spot for Farense.
