Odd situation since it isn't something you'd expect Cesc to do, and it isn't something you'd expect Brian Horton to complain about if it wasn't legit.
The FA are probing the case but I don't think they'll find any solid evidence whether Fabregas did it or not.
And that made it ok for Keown to do what he did? Keane would kick people, not spit at people. If I recall correctly, Vieira spat at someone.
