English football hooligans haven't helped a joint bid between Ireland and the UK for the 2030 World Cup, according to the Taoiseach.
Fans without tickets barged into Wembley Stadium last Sunday for the Euro 2020 final between England and Italy.
While videos of violence around the ground caused outrage on social media.
The Taoiseach believes the UK is still capable of hosting major tournaments:
"obviously sporting authorities take those matters very seriously and it doesn't help in terms of bidding for events into the future because crowd control and the organisation around that is a key issue. That said, the London Olympics was a superb organising achievement" according to Micheál Martin.
Meanwhile, another person has been arrested as part of an investigation into racist social media messages posted after England's Euro 2020 final defeat.
Cheshire Police say the 42-year-old is being questioned on suspicion of writing material likely to stir up racial hatred.
It brings the total number of arrests following the match to five.
