I don't understand why i so often read that Warnock has had a 50% success rate in the transfer market cos these two players have been failures.

Let's remember that Warnock brought in all 4 players when the transfer window was shut so his options were severely limited.

Secondly these 2 players were given two month contracts so they are basically trialists.

Hoilett was given a contract til the end of the season and Bamba til the end of next season.

Chamakh and Richardson were given a chance by Warnock to prove himself and in my opinion can only be called bad signings if Warnock decides to extend they contracts in January which i very much doubt he will.
