Real Madrid suffered a double injury blow on Tuesday ahead of their Champions League quarter-final clash with Liverpool next month.
Neither have been ruled out altogether, however, both face a race against time to prove their fitness after Valverde has suffered a muscular injury and Kroos suffered an adductor injury whilst away with Germany.
Valverde, a 22-cap Uruguay international, has made 22 appearances across all competitions this season and the 22-year-old has been a growing influence in Zinedine Zidane’s squad.
Liverpool are all too familiar with injury issues this season and many Reds would perhaps be pleased to see upcoming opposition struggles.
Valverde’s absence would no doubt be a blow to Real, but football fans worldwide are au fait with Kroos’ abilities and he would be a huge loss to the La Liga giants.
Jurgen Klopp will have little to no sympathy for the Spaniards, as the Reds boss is unlikely to have Jordan Henderson back and available, not to mention his long list of defensive casualties.
