Ghana defender Daniel Amartey was in action for Leicester City as their Europa League campaign came to end after a 2-0 aggregate loss against Sparta Prague on Thursday.
The Foxes were heavily tipped to advance to the next stage of the competition as they are the Premier League’s third-best side.
But on a night that will hopefully not be beaten as the most disappointing of the season, they were beaten by a more organised and ultimately better team.
There was no fortune in Slavia’s success at the King Power Stadium, secured with second-half goals from Lukas Provod and Abdallah Sima.
Amartey, who was deployed as a right-back, did not do anything wrong, but his lack of attacking instincts unbalanced Brendan Rodgers’ side and it made them much easier to defend against.
The 26-year-old was replaced with Ricardo Pereira in the 61st minute.
He has played nine times in all competitions for the club.
