Arsenal had one foot in the Champions League last-16, but somehow managed to blow it.
They led Anderlecht 3-nil in the second half of their group clash last night, only for it to end 3-3.
With two games to play Arsene Wenger's men must beat either Borussia Dortmund or Galatasaray to guarantee their place in the knock-out stages.
Liverpool will likely need to win both their remaining matches after a 1-nil loss to Real Madrid.
Tonight, Chelsea could claim a place in the last-16 with victory at Maribor.
Manchester City are desperate for a win at home to CSKA Moscow.
