Inigo Calderon is on standby to take a penalty for Albion against Crystal Palace at The Amex today.


  Regular taker David had been substituted when Leo Ulloa had a spot-kick saved in Tuesday's 2-1 defeat at Barnsley.


  Fullback Calderon is in the frame if history repeats itself and Albion are awarded a penalty against Palace in their noon showdown with David off the pitch.


  Manager Gus Poyet said: "Somebody needs to step up. There are players that are quite good. In particular I like Calde. People think strikers need to take them, offensive and technical players. Maybe you'll see Calde taking it.


  "I have seen him practise, because it is part of training. Not daily but there are plenty of games, competitions, players staying after and they are always taking penalties and I like the way Calde takes penalties. That doesn't mean he is going to score or miss.


  "Of course, we have got a player that is unique in David but you cannot keep a player on the pitch all the time somehow, because he takes penalties."


  Albion and Palace have both scored from the spot in the last two clashes between the clubs.


  Glenn Murray and Owen Garvan converted penalties in the Seagulls' 3-0 defeat at Selhurst Park earlier this season.


  Ashley Barnes equalised from 12 yards for Albion in the corresponding fixture last season after Chris Martin put Palace ahead with a penalty.
