The clash on October 24 has been ordered by Uefa to be played behind closed doors because of previous racist behaviour from fans of the Slovakian club.

However, the hosts could have up to 15,000 under-14s from schools and football academies attend the match free of charge, in line with Uefa rules.

And the Express & Star has been sent the regulations from European football's governing body which also state 'a maximum of 200 people holding category one tickets from the visiting club or association' can attend behind-closed-doors matches.
