Problem with putting 2nd string side is that it shatters their confidence if battered as in case of Dortmund last year, which in place ruins Poch's confidence for selectin 'em again. Putting a balanced team with First teamers and 2nd strings and losing gracefully may help in long run. Expecting similar intensity from 2nd string will only result in mental collapse of our squad.
I believe that our performance towards last year's end was mental and not physical.
They have to learn, no point wondering if the likes of Winks, CCV and Onomah are ready if we are not prepared to use them, like Kane in the EL all those years ago it's there chance to show they should be in the first 11. If they are not good enough then we will at least know.
