Both managers are desperate on extending their participation in one of the most prestigious cup competitions when they meet at the Hawthorns on Saturday.
West Brom boss Tony Pulis has got the option with his improved Nigerian forward Brown Ideye's scoring touch but on the other side West Ham boss Sam Allardyce's injury problems have been a major concern as the England forward Andy Carroll suffered from his knee injury during the 0-0 draw against Southampton on Wednesday night.
The 28-year-old Adrian has been ins excellent form between the sticks for the Hammers, the Spaniard could miss the game and his absence would be a huge blow for the Londoners.
West Brom Albion are remain the favourites for this fixture despite their league position, especially if we consider West Ham's injury problems.
However, the Hammers were hard to beat in their last two Premier League games, draws with Manchester United and Southampton, that means Allardyce’s side have lost only 1 in their last 9 games in all competitions.
Allardyce is confident that the club skipper Kevin Nolan and the attacking midfielder Mark Noble will ease the club's injury crisis in the Sixth Round on Saturday.
Pulis’ side have won their home game by 2-0 against Swansea in the league during midweek and drew away against West Ham on New Year’s Day.
The Baggies are in good form under their new manager has a good record with 4 wins, 2 draws and a defeat through their past 7 fixtures and Pulis seems hopeful from the fact that his squad beat West Ham.
Six of these sides last 10 meetings have been drawn, the Baggies key player would be Saido Berahino, who has scored 15 this season and trades 8/5 in the betting market.
