I find this game interesting because both clubs with problems ahead of Wednesday's Cup clash.
The club authorities revealed crippling debts of over 1,170 million euros while Rayo's have troubles of their own, in relationship between the players and the board that the squad issued a communiqué complaining about a lack of communication after the last round of the Cup. They were also unhappy about being forced to start a coach journey to play Mirandes in the middle of a snowstorm, which saw them become trapped in the snow before eventually being forced to turn around.
Good news is that Lionel Messi has returned to the Barcelona squad having sat out two matches through suspension.
Overall Rayo will be motivated as any other team who has to compete against famous Barcelona, so some sparks expecting in this clash as well.
