Marc Bartra described the bomb attack on the Borussia Dortmund team coach in which he was injured as the “hardest 15 minutes” of his life.

The 26-year-old is in hospital recovering from an operation on a wrist broken by the explosion, which is expected to sideline the centre-back for four weeks. Bartra was the only player to receive serious injuries in Tuesday’s blast, which happened as the team travelled to the Westfalenstadion for the first leg of their Champions League quarter-final against Monaco.

The Spain defender took to Instagram to describe the experience after a visit from his family. “They are my everything, the reason I struggle to overcome obstacles and this has been the worst of my life, an experience I would not want anyone in this world [to have],” he wrote. “The pain, the panic and the uncertainty of not knowing what was going on, or how long it would last … were the longest and hardest 15 minutes of my life.

“I think the shock is decreasing more and more and, at the same time, it adds to the desire to live, to fight, to work, to laugh, to cry, to feel, to love, to believe, to play, to train, to continue to enjoy my people, loved ones, companions, my passion, to defend, to smell the grass as I do before the game starts and motivate me. The only thing I ask is for everyone to live in peace and to leave behind the wars.

“These days when I look at my wrist, swollen and badly wounded, you know what I feel? Pride. I look at it proudly, thinking all the damage they wanted to do to us on Tuesday stayed in this. Thanks to the doctors, nurses, physiotherapists and people who helped me recover.

“To the thousands and thousands of people, media, organisations of all kinds, the club and colleagues, who have given me your support and affection – as small as it may be – has filled me with incredible strength to continue on and on. I needed to write and unburden myself and to settle everything so I can just think about getting 100% as soon as possible.”
