Blimey, this thread has really open up a can of worms!, I don't think it should bother anyone if he wants to boast his achievements, he is new and only making talk, other managers with much more experience can boast back, sure he will fall on his sword eventually as everybody does in this game, if he stays long enough in the current way of playing will be a miracle!. We should encourage him to play as we do lol, I haven't even come close to the treble, I never try! I'm only here for the league and the cups are extra training to give my fringe players game time, anyway he is happy at what he has done and the game has achieved its goal in hooking him in!, as long as he is enjoying it fair play and good luck to him.
Well done getting the treble bud just don't do it if we ever cross LGS lol.
