We (at NU-Mad) understand Johnson's frustration at the lack of first-team opportunities, but we believe (from our Middlesbrough connections) the former Smoggy is happy with his lot at City - and certainly not homesick.
The former Middlesbrough wideman struggled for regular appearances and that lack of opportunity cost Johnson (what once appeared to be a) certain place in England’s squad for Euro 2012.
Johnson could add creativity to any team, but Newcastle already have class in his position.
However, Danny Guthrie is on his way, and Johnson would be the perfect replacement.
Apparently, Sunderland would be willing to sign the England international either on loan or on a permanent deal.
His estimated £50,000-per-week wages may prove a stumbling block but owners Man City may subsidise his salary if he moves on loan.
