West Ham United midfielder Joe Cole is being tracked by a number of MLS clubs after reports he could leave the Hammers in January.

Cole was said to be furious after he was subbed off before half time by Irons boss Sam Allardyce in the 3-0 defeat against Chelsea.

Although the 32-year-old reiterated his loyalty to West Ham yesterday, Chicago Fire, DC United and FC Dallas are monitoring Cole's situation.
