West Ham boss Sam Allardyce has hinted that rival English Premier League clubs might have broken transfer rules by "tapping up" Winston Reid.
Reid is out of contract with the Hammers in the off-season and has so far failed to agree to new terms at Upton Park.
FIFA transfer rules allow Reid's handlers to only speak with foreign clubs, yet Reid - who has been one of the best performing defenders in the EPL this season - continues to be linked to English giants Arsenal, Liverpool, Manchester United and Tottenham.
"He's only allowed to speak to foreign clubs. But can we prove it?" the BBC reported Allardyce saying when the topic was raised at a media conference before West Ham's FA Cup clash with Everton.
"We have had them [regulations] for a long, long time. If you can prove that they [clubs] have broken the rules, then they are in serious trouble aren't they? But you can't prove it these days. You hear rumours, this, that and the other.
