Arsenal legend, Paul Merson has questioned Barcelona’s move for Chelsea centre-back, Andreas Christensen, insisting that the player might have a mental health issue.

Christensen is set to join Barcelona this summer after his contract with the Blues expires in June.

The Denmark International has reportedly agreed to a five-year contract worth €5 million per season with Barcelona.

However, after his shocking absence from Chelsea’s FA Cup final defeat to Liverpool last weekend, Merson wondered if Barcelona is making the right decision to sign the defender.

“Barcelona must wonder what they’re buying after Andreas Christensen’s no-show in the FA Cup final. You don’t know the real reason for him doing what he did,” Merson told Daily Star.

“He might have a mental health issue, and then you hope he’s alright and wish him well. But if you are Barcelona, you don’t want to be signing a player who doesn’t want to play football.”

He added, “If he does have a mental health issue, you would like to think he would come out and speak about it if only to help other people who might be struggling. But he’s let Chelsea fans down because since he agreed to join Barca he has literally gone downhill.

“Look at Antonio Rudiger. He’s agreed to leave as well. And don’t tell me he didn’t make his mind up months ago. But he’s still been nine out of ten every week. Some people can concentrate and some people’s heads get turned. And you’d be disappointed if you were one of Christensen’s teammates.”
