At first it made no sense and made me a bit nervous since he's really our only other left back, and when we played Agger there in the final minutes of the City match, we lost.. That said, he looks solid at times and shaky at others, but needs the game time, so the way I see it, with Coutinho having impressed so much as a starter right away up front, we're loaded up there in Suarez, Sturridge, Coutinho, Sterling, Downing and even Henderson/Suso. So, that essentially relegates Downing back to reserve LB, and at least knowing Wisdom can do a job at RB, then Glen is first up to switch over. Plus, while I don't know the date, Kelly has a return in mind too..
I think next season, we could be really packed back there with another CB and left back.
That was the key for me Jase, Kelly is training with the ball again now and will return in March by the looks of things (that is when our next league game is anyway!). For me, Downing, Johnson and Agger are better equipped for us at left back then Robinson right now so the loan was a nessescity really.
