The draw for the Champions League Round of 16 will be held this next Monday and Real Madrid will have their fate sealed.
PSV, Benfica, Juventus, Roma, Arsenal, Dynamo Kiev and Gent will be the teams available for Real Madrid. Other big clubs like Manchester United and FC Porto couldn't manage to make it through the Group Stage and that obviously benefits Real Madrid down the road.
Arsenal and Juventus are arguably the two toughest teams in that draw, with Roma and Benfica one step below. It would be tough to face them in the Round of 16 while a meeting with teams like Gent or Dynamo could make things much easier for Los Blancos.
Either way, Real Madrid will not have a very busy schedule after being disqualified from the Copa del Rey, so Benítez should have his players fresh and ready to win no matter the team they draw next Monday.
