Real Madrid's Dani Carvajal expressed his concern that Los Blancos' Champions League final could be "tainted" by the "chaos" of the crowd problems at the Stade de France.

The showpiece on Saturday, which Madrid won 1-0 to claim their 14th European Cup, was twice delayed before kick-off due to crowd congestion, with UEFA initially citing "security reasons".

Liverpool fans complained of heavy-handed policing outside the stadium, suggesting tear gas or pepper spray had been used on supporters. A number of British-based journalists reported first-hand accounts of witnessing poor organisation and inappropriate behaviour outside the stadium by French authorities.

The Premier League club subsequently requested a formal investigation, while UEFA blamed the delays on fans trying to use "fake tickets" to gain entry.

UEFA has since commissioned an independent inquiry into the events in Paris, with Liverpool chairman Tom Werner demanding an apology and assurances the French authorities will cooperate with the investigation.

Carvajal's family were present at the final and the Spain international detailed the unsavoury scenes outside the ground as he called for change.

"There was quite a bit of chaos," Carvajal said on Tuesday at a pre-match press conference with Spain ahead of their Nations League game with Portugal.

"Our closest relatives – my parents, my wife and my son – had to be left practically at the door of the stadium because security getting in couldn't be guaranteed.

"It's a shame that because of something external the final could be a bit tainted.

"It must be noted and corrected for the next events that take place at that stadium. It needs to improve, because there were people that suffered a lot.

"It should have been a dream day, whether you win or lose, and there were people who couldn't enjoy it."
