Gero, Fyfe is getting banged about as well, and needs a break from that. At CHF he will be JAM (just another midfielder) Put him to FF and he is less likely to be smashed around, get clean, open contests, and his goalkicking might just improve if he is not doing continuous beep test runs.
As for the myth our midfield is a problem and needs Fyfe, it ain't, and it doesn't. If you use a screwdriver to try and hammer in a nail, it don't work, if you use a hammer to screw in a posidrive screw, it don't work. If you use a midfield to play as defenders/forwards, with the running that entails, it don't work. Use our midfielders in the middle, and if you want midfielders (eg Fyfe/ Mundy) to play forward, place them there and put someone else in the middle.
Get some real structure into our play/positioning and back our player to beat his opponent, Lyon's tactics are only necessary if you think you can't win one on one, and are trying to limit the loss. We have proved we can match it with the best, so let the players loose. Otherwise, Yeti will have plenty of room on that "membership slide" down at Cockburn.
