Diego Simeone has voiced his concern that his side might be fatigued going into their game against Betis following their hard-fought Copa del Rey semi-final victory over Sevilla on Thursday.
Atletico's squad comprises of players such as Radamel Falcao, Arda Turan, Emre and Juanfran, but the Argentine coach believes that they could suffer at the hands of La Liga's fifth-placed side due to fitness levels.
