Don't fancy Bassong at LB, he's played (on the whole) well along side Daws at CB this season, I don't see any sense in moving him. BAE is a good left back, he was having a great season before his injury but he is still solid in my opinion. Yes he has "issues" with his temper and is prone to the odd strange tackle, however BAE is a much better than average LB where as Bassong would only be in the "to do a job category LB" I feel the situation we are in at the moment regarding the number of games left, we can't afford to be making needless changes to our defence.
If Harry was to drop BAE then there can only be one player who will take his place and thats Bale. If Bentley and/or Hudd are back tomorrow then Bale could slip back to full back with Modric on the left, Bentley on the right and with Hudd and Wilson in the centre again.
