Evertons long-serving goalkeeper Tim Howard has come under fire from sections of the fan base of late, with the American allowing errors to creep into his once-sturdy game. Although Martinez continues to stand by the former Manchester United stopper, there have been calls for him to be dropped, and the Blues have been linked with Cardiff Citys David Marshall and Ukraine international Denys Boyko as potential replacements. With Howard approaching his 37th birthday and harbouring ambitions to play on until 2018, could this be his final season at Everton? Perhaps the slower pace of Major League Soccer would be a more accommodating stage for the twilight years of his career.
