Barcelona have signed a pioneering sponsorship deal with computer company Intel.
The Intel logo will appear on the inside on the jersey. But, players are under no obligation to reveal the advertisement after scoring.
It will cost Intel £25 million for four years.
Barcelona never allowed shirt sponsorship for 111 years. That ended in 2010, and now they have sponsorship on both the front and the inside of their strip.
The computer company say that the move is a lot more than just the advertisement inside the shirt. They claim the collaboration between the two organisations will make Barça one of the most technologically advanced clubs in the world.
