Head coach of English "Everton" Sean Dyche explained why the Ukrainian defender of his team Vitaly Mikolenko asked for a substitution in the middle of the first half of yesterday's match with "Aston Villa" (2:3), which was held within the framework of the 4th round of the championship of England.
"It's just a general illness. Something more specific can be said when the disease fully manifests itself.
Mikolenko felt bad, so I realized that he had to leave the field," - quotes Dyche official website of Everton.
