Due to the severity of the injury, an operation is required following the immediate treatment in Columbia. This will be performed by a specialist in Madrid by agreement with Bayer 04, Arias and Atlético. The 28-year-old Arias is expected to fly from Colombia to Spain in the middle of next week.
“This serious injury hits us hard and affects everybody. Santiago is a great character and has joined us with great ambition and it’s a bitter blow for him,” declared sporting director Simon Rolfes. “Like Atlético Madrid, we will do everything we can to support Santiago in his recovery. After the operation and his return to Leverkusen, he will be looked after by us during his rehab. Our medical section and the whole club are behind him so that he can return fully fit as soon as possible.”
“I can’t describe how I feel. I’d be lying if I said I’m doing alright but I don’t want to maintain the opposite. I’m sad about the situation,” Arias said on Instagram on Saturday. “This is another test to overcome and it will make me stronger. I promise to work hard to get back quickly and stronger and be able to wear the colours of Colombia and my club Bayer 04 Leverkusen again.”
