Manchester City’s ongoing attempts to fall in line with Financial Fair Play could scupper a deal for Real Madrid goalkeeper Iker Casillas, [football] direct news understands. The 32-year-old is on the Blues’ radar, although a source close to the Etihad Stadium told FDN that current number one Joe Hart has impressed staff with his attitude and performances since returning to the side in January. England star Hart was dropped for six weeks following a howler in the 2-1 loss at title rivals Chelsea in November, but has been on form since winning back his spot and has kept five successive Premier League clean sheets. Should Hart ask to move on at the end of the season, Casillas will feature on a shortlist of potential replacements, but according to the source, the fear at City is that the Spain international’s wage demands will be too high.
