The Copa del Rey's semi-final pairings will be known this Friday at 13:30 CET, after the Estadio Benito Villamarin was chosen by the RFEF this week to host the final.
There will be a 20-day intervening period between the first and second legs (February 6-27), during which the first leg of the first Champions League knockout round and the Europa League's round of 32 will be played.
Barcelona, Valencia, Real Madrid and hosts Real Betis are the four teams to be rewarded by being included in the draw after suffering through a testing January.
Should Barcelona be paired with Madrid, there will be two Clasicos played in a four-day period - on February 27 and March 2 - as they meet in round 26 of LaLiga Santander.
The Azulgrana completed an astonishing quarter-final turnaround against Sevilla with a 6-1 win at the Camp Nou on Wednesday as they continue to go in search of three trophies this season.
Madrid won their last two Copa crowns at Mestalla in 2010/11 and 2013/14, both coming against the Catalans in the final.
Los Che, meanwhile, have seven titles to their name and last lifted the trophy in the 2007/08 season.
Betis have dreams of lifting their third Copa del Rey in front of their own fans for the first time since 2004/05.

If this happens it will be so unfortunate for Madrid; after all the good spells in CDR, Barca will not allow them get to the final. Madrid fans start fasting and praying that this doesn't happen... [Spittongue]
