This weekend we have seen 3 awful over the ball challenges by players trying to sheild the ball with their body. To be fair to the players involved neither Julio Arca or Emmanuel Adebayor (twice) seemed to go out of their way to "do" the player but were still very dangerous acts of play (Arca's challenge on Andrew Johnson was sickening). All three challenges resulted in yellow cards when they should have been red cards. Studs were showing in all 3 challenges which would normally result in a red card in todays game if the tackles had been sliding tackles on the floor. These fouls were half way up the skins so are worse imo. Its time these tackles were taken out of the game before someone gets seriously injured.
