Dean Henderson
Henderson has already been on Tyneside this month in an effort to accelerate a protracted move to Newcastle that was first mooted in January. The 25-year-old would have no issue leaving United permanently but the club's preference is for a(nother) loan, which is not a total ringing endorsement of David de Gea as he approaches the final year of his contract (with a one-year option).
United have Henderson under contract for a maximum of another four years and he earns in excess of £100,000-a-week; stumbling blocks to a permanent transfer. The word from Henderson's side is United are the biggest 'stumbling block' as they seek guaranteed back-up to offset his likely exit.
