Atletico Madrid boss Diego Simeone has discussed the differences between Real Madrid and Barcelona.
Atletico meet Barca in the Copa del Rey tonight.
Simeone said: "[Real] Madrid and Barcelona have extraordinary qualities. Perhaps one side is stronger in spaces, whereas Barcelona are much more dangerous in confined spaces.
"While against Barcelona you are closer to your own goal and there is more risk that they can combine and form triangles that surprise you day after day."
