Real Madrid midfielder Toni Kroos admits he didn't expect his recovery from injury to be as rapid as it was, following his appearance against Borussia Dortmund in the Champions League.
The Germany international was set to be sidelined for up to six weeks after sustaining a hairline fracture in a La Liga encounter against Valencia, but the former Bayern Munch appeared as a second-half substitute in Wednesday's 2-2 draw with Dortmund.
"The recovery process has been really quick," he told the DFB's official website. "It's pretty difficult to predict the recovery time for this kind of injury.
"Several doctors had predicted that the hairline fracture would need to heal for longer and that I would be out for a while. But it's gone very quickly for me and I felt good so I went back to training with the first team.
"I'm really pleased that my coach Zinedine Zidane has put his trust in me again so quickly. I felt fine during the 30 minutes that I was on and didn't have any pain at all," he concluded.
Kroos has been included in Zidane's 23-man squad which will duty in the FIFA Club World Cup, with the 26-year-old looking to clinch his third title after wins in 2013 and 2014 with Munich and Madrid respectively.
