The Hammers have been plagued by injuries and suspensions so far this campaign, but Allardyce is able to pick his strongest possible team for the trip to the Britannia.
The manager consistently claimed that once he had everybody back to full fitness the team would climb the table, and impressive recent run has seen them move into the top half of the table, having been in the relegation zone before Christmas.
Latest injury victim Ricardo Vaz Te, who suffered a knee injury following a shoulder dislocation, was today reported as being fit for selection on Saturday.
That gives the manager a selection headache and with his options so strong, Allardyce is unlikely to start the player, who may find himself on the bench.
A source told said: “This is a huge relief for the manager because with everybody fit we are a match for any team in the league.”
