"Our joint advice to Middlesbrough Football Club is to sell the match tickets as part of a complete travel package only.
"The disorder we witnessed in Zurich reinforced our concerns and this option will go a big way to ensuring the safety of our supporters."
A spokesman for Middlesbrough Football Club added: "On the advice of police in Cleveland and in Holland, as well as the football authorities, our ticket allocation will only be made available to those travelling with the trip organised on our behalf by TravelCare Sports.
"We understand that, despite our earlier advice not to do so, many fans have already made their travel arrangements, but we trust supporters will understand that we must follow the advice we have been given on safety grounds."
