He added: "I don't know for the life of me what that squad will look like when I name it in May because I don't know what players will be available".

Spain is the only team to have won the competition consecutively - in 2008 and 2012.
A match against Poland might make for an interesting sideshow for Swansea City fans as it would pair Neil Taylor and Ashley Williams against team-mate Lukasz Fabianski.

The 2014 World Cup champions open against Ukraine on June 12 in Lille.

"We know our opponents". Of course we can dream, like Greece and Denmark once did [winning Euro 2004 andEuro '92 respectively].
