Sorry but can't understand the negativity on thus forum in relation to Kean substitutio..of course he is a far more skikful llayer than niasse but the teenager dud not appear to understand what Ferguson demands from a player wearing the Everton shir...I wstched the game on Tv an during the 15 or so minutes Kean was on the pitch I can't remember him offering the sort of attitude demanded by Ferguson and which had been displayed by the rest of the team during the whole game...Niasse did more in the few minutes he was on than Kean did ...the answer is quite simple. .while Ferguson is in charge you work your balls off or suffer the consequences
