Ralf Fahrmann outshone Iker Casillas on the Spaniard's landmark Champions League appearance, as Schalke drew 1-1 with Porto in Group D.

Ralf Fahrmann's fine display was not enough to earn Schalke a win as Otavio's penalty helped Porto claim a 1-1 draw in their Champions League Group D fixture.

Iker Casillas became the first player to feature in a 20th Champions League campaign, but it was Fahrmann who left his mark at Veltins-Arena with a string of superb saves.

Having brilliantly kept out Alex Telles' spot-kick, Fahrmann somehow denied Felipe from point-blank range early in the second half before Breel Embolo nudged Schalke ahead just after the hour.

Fahrmann could not repeat his earlier heroics in the 75th minute, though, as Otavio stepped up to convert from the spot and secure a share of the spoils after Naldo had clumsily brought down Moussa Marega.

With all eyes on Casillas, it was Fahrmann who took the limelight in the 13th minute, getting down low to tip Telles' shot wide after referee Jesus Gil Manzano deemed Naldo had deliberately handled in the area.
