Both are away matches. So a lot of recovery time is lost in travel. Besides, no players can fully recover and be 100% within that time frame. This is when squad depth matters but unfortunately it's something that we lack in ETH's first season.
Not saying it’s easy, just pointing out that the semi is on Sunday. We’ve done this Thursday-Sunday for a while anyway. Hope we beat Sevilla by two or more goals at home so we could (although EtH probably wouldn’t) rest some players in the away leg.
