Bayern Munich and Olympiakos meet on Tuesday knowing a draw would take both through to the Champions League last 16 and eliminate Arsenal.

Hosts Bayern are likely to be without left-back David Alaba, who has an ankle injury, for a game boss Pep Guardiola calls "a bit like a final for us".

"We know how strong Olympiakos are," said the ex-Barcelona boss. "They play good football.

"We can qualify for the next round as the top side in the group [if we win]."

Bayern are top of Group F on nine points, level with Olympiakos, after four of the six games, with Arsenal third on three points.

Guardiola added: "They will not allow us much space, especially in front of their goal.

"Their wingers are very quick and they have some tall players too."

Olympiakos did not play on Saturday after the Athens derby against Panathinaikos was called off following crowd trouble.
