Barcelona were made to work hard against Athletic Club in La Liga on Sunday evening, but they eventually secured a 1-0 victory thanks to a stunning debut goal from substitute Marc Guiu.

The 17-year-old came off the bench with just 11 minutes remaining and made an instant impact, racing down the left channel before slotting a fine finish past Unai Simon. It was a moment of pure brilliance from Guiu, who had only made two full appearances for Barcelona B prior to this game.

Barcelona's victory moves them to within one point of leaders Real Madrid at the top of La Liga, and it will be a huge confidence boost for Xavi Hernandez's side ahead of next weekend's Clasico.

Talking Point: A Star is Born

Marc Guiu's performance against Athletic Club was a sign of things to come. The 17-year-old is a tall and powerful striker with excellent technical ability, and he has the potential to be a future star for Barcelona.

Guiu's goal against Athletic Club was a perfect example of his talent. He showed great pace and awareness to make the run behind the defence, and his finish was clinical. He also looked comfortable on the ball and showed good link-up play with his teammates.

Given his age and inexperience, it is important to be patient with Guiu, but he has already shown that he has the potential to be a valuable asset for Barcelona. He could be a useful backup option for Robert Lewandowski this season, and he could even challenge for a starting spot in the future.

Player of the Match: Marc Guiu

There were a number of impressive performances from both teams in this match, but Marc Guiu was the standout player. His goal was the difference between the two sides, and he also looked very good throughout his time on the pitch.

Goalkeepers Marc-Andre ter Stegen and Unai Simon also deserve praise for their performances. Both players made a number of excellent saves to keep the game goalless for long periods.

Overall, it was a very entertaining match, and Barcelona will be delighted with the three points. They will now be looking to build on this momentum and secure a victory in next weekend's Clasico.
