Leicester City sack Claudio Ranieri
It comes just nine months after leading the side to Premier League victory.
The Foxes took the Premier League title by 10 points but have struggled to keep up that form.
They have only won five top-flight games this season, and could become the first defending champions to be relegated since 1938.
They're currently just a point and a place above the relegation zone.
In a statement, the club call him their most successful boss of all time - but say a change is "painful" and "necessary".
The 65 year old Italian's departure comes less than 24 hours after a 2-1 defeat at Spanish side Sevilla, in the first leg of their Champions League last-16 tie.
