Inter midfielder Wesley Sneijder has revealed he is currently suffering from anaemia and that is partly why he fainted in the dressing room on Saturday.
Interviewed in Duth newspaper De Telegraaf, the 26-year-old claims he is exhausted after this year's efforts in Serie A, the Champions League and the World Cup.
"I have anaemia, but it's nothing bad," he said.
"I started to shake throughout the first half. I had pain in every part of my body.
"I visited the cardiologist to check the [blood] pressure. Then I went to Holland for a second opinion.
"The conclusion is that I am suffering from anaemia and my body is tired. I need rest, but now I can't really abandon my teammates.
"We have too many injuries in midfield."
Sneijder has not been selected for this evening's clash with Lecce, but is expected to play in the Derby della Madonnina against Milan on Sunday.
