Conte and Costa at loggerheads after substitution row

A clash of egos is almost inevitable with Antonio Conte and Diego Costa, with the Chelsea pair at eachother's throats following a dispute towards the end of the Blues' 3-0 win over Leicester City on the weekend.
After securing a comfortable lead early on in the match, Chelsea took their foot off the pedal somewhat, much to the coach's displeasure with Costa's request to be taken off tipping Conte over the edge.
As a result, an argument broke out in the dressing room leading to others intervening in an attempt to calm the situation.
Both characters are strong-willed and often confrontational, creating great tension in their exchanges, but the reality is that they need eachother.
Understandably, Conte doesn't want his players to relax before the final whistle and has taken aim to Costa's professional pride to make his point.
However, the Spanish-Brazilian forward is comfortably Chelsea's top striker and leading scorer, making him undroppable and certainly unsellable, making this scenario one that will likely have to be confronted many times in the coming weeks and months.
