Alemao to score

Alemao has scored four goals in the Conference League for Rayo Vallecano this season, more than any of his teammates. The Brazilian forward is in good form right now, finding the back of the net five times in his last eight matches in league and cup.

Pathe Ciss to be carded

Pathe Ismael Ciss has received the most bookings of any Rayo Vallecano player in the Conference League with four to his name. The 32-year-old has committed 1.1 fouls per game in this competition and has been booked five times in his last nine matches.

Jean-Philippe Mateta: 1 + Shot on Target

Jean-Philippe Mateta is averaging 1.19 shots in target per 90 minutes in the Conference League this season, despite only scoring one goal. The French international striker has landed at least one shot on target in five of his last eight matches for the Eagles across all competitions.
