Leicester City fans chanting 'You Spanish b******s, Gibraltar is ours' clashed with police in Madrid ahead of their Champions League match tonight.
Spanish police stormed a major square in the country's capital after smoke bombs and flares were let off and bottles were being smashed.
Around 4,000 supporters of the English champions are said to have travelled for the quarter-final against Atletico Madrid.
The supporters were in good spirits earlier in the day in Plaza Mayor, enjoying the warm sunshine and refreshments in Madrid.
