Worst PL players "stealing a living"?

Dont know if still play but i remember Karl Henry of QPR... Still haven't seen a worse player than him
 
I’ve seen Premier League to League 2 to non-league matches. I’ve seen Preliminary Round FA Cup games, and I maintain that the worst player I have seen in person is Theo Walcott. This was 7 years ago, but the gulf in technique and ‘football intelligence’ with the other players on the pitch (including Bendtner, Eboue and Silvestre) was extraordinary.
