UEFA insists this week’s Champions League quarter-final ties will go ahead as scheduled amid an Islamic State terror threat.

Arsenal’s Emirates Stadium will host the first leg of the Gunners’ last-eight tie against Bayern Munich on Tuesday evening, while Manchester City are also in action away to Real Madrid.

A media outlet linked to the terror group has issued a threat concerning all four of this week’s ties, and European football’s governing body UEFA has now issued a statement on the matter.

“UEFA is aware of alleged terrorist threats made towards this week’s UEFA Champions League matches and is closely liaising with the authorities at the respective venues,” the statement said.

“All matches are planned to go ahead as scheduled with appropriate security arrangements in place.”

The Metropolitan Police issued a release stating it had a “robust” plan in place for the Arsenal game.

Deputy Assistant Commissioner Ade Adelekan, who is overseeing the policing of London on Tuesday, said: “The UK terrorism threat level remains at ‘substantial’ meaning an attack is likely, and we work closely with colleagues from across Counter Terrorism Policing in planning for events here in London, to take into account any relevant information that could help us to keep those attending safe.

“We’re aware of online and media reports in relation to calls to target matches across Europe and here in London. However, I want to reassure the public that we have a robust policing plan in place for tonight’s match and we continue to work closely alongside the club’s security team to ensure that the match passes peacefully.

“As ever, we ask the public to remain vigilant, and if they see anything that doesn’t look or feel right, then report it to police or security staff.”

An Arsenal spokesperson said: “We work closely with the Metropolitan Police regarding the safety and security of all supporters and staff at Emirates Stadium for all our matches.

“Our planning for tonight’s fixture is no different and our approach, working together with the Police and UEFA, is proportionate to the current UK threat level.”

The UK Football Policing Unit has also been contacted for comment.

Islamic State claimed responsibility for the attack on the Crocus Hall concert venue outside Moscow on March 22 in which 144 people were killed.

Luis Enrique, the coach of Paris St Germain who host Barcelona at the Parc des Princes on Wednesday evening, said at his team’s press conference: “I hope it can be controlled and I hope it’s just a threat and that nothing will happen.

“Of course we are concerned.”

PSG player Danilo added: “Security is always important, not just for us as the players, but for everyone, for everyone who loves sport and this game.

“I do think that’s important, but we do have to focus on what we need to do, playing football. There are other people who need to focus on everyone’s safety and security.”
