If you thought Antonio Valencia's swollen eye was bad following an early clash of heads in Manchester United's Champions League match against Olympiakos last night, then spare a thought for Zenit St Petersburg defender Tomas Hubocan, who suffered a horrific head injury after a challenge with Robert Lewandowski in Germany last night.
The 28-year-old defender was laid out on the ground and covered in blood after suffering a huge gash against Borussia Dortmund on Wednesday evening, when the Polish striker's knee accidentally caught his opponent on the side of the face.
Hubocan required extensive treatment in the closing minutes of the last-16 second leg clash, before returning to the field with head bandaged up to play to the final whistle.
But, even after putting his body on the line, the Slovak was left disappointed at the end of the game, as the Russian giants crashed out of Europe's elite club competition - despite a 2-1 win against Jurgen Klopp's side on the night - with last year's finalists progressing to the quarter-finals with a 5-4 aggregate victory.
