The growing waves of break-ins to senior player's houses, especially at clubs such as Real Madrid and Atletico, have put the two teams on high alert.
Both teams had already given their players advice to follow, but now the whole thing has gone a step too far.
'Marca' reports that the National Police will meet with the people in charge of security at Madrid and Atletico to make decisions in order to avoid new break-ins from happening.
The Spanish capital is in the spotlight, because, despite player's house being broken into from other teams, such as Barcelona, the centre of the theft operations seem to be in Madrid.
The authorities have indicated in red the areas of La Moraleja, Mirasierra and Majadahonda. In addition, they will urge footballers to increase private security measures in their homes as well.
