Anton Ferdinand has revealed he is 'buzzing' ahead of his return to West Ham's first team.
The defender has been out of action for two months with a hamstring injury, but he could make his comeback in Saturday's match with Manchester United at Upton Park.
Ferdinand was named as a substitute in Boxing Day's draw with Reading and he has admitted he has found his spell on the sidelines hard to take.
"It's been very frustrating," Ferdinand told Sky Sports News.
"It is the longest I have ever been out with an injury and I'm not one that likes to watch. I get more nervous watching the boys than I do when I'm playing.
"But the time is over for me to sit back and now I'm back involved and I'm buzzing really."
West Ham have been badly hit by injuries this season and they remain without the likes of Lee Bowyer, Kieron Dyer, Julien Faubert, Matthew Etherington, Bobby Zamora and Craig Bellamy for the visit of United.
And Ferdinand admits he feels sympathy for his manager Alan Curbishley, but he has praised the strength of the Hammers squad who have steered the club to 10th place in the Premier League despite the ongoing injury woes.
"A lot of the players that are injured now are key players to the team and that is hard for the manager," Ferdinand added.
"But credit to the boys that have stepped in. That shows that the squad has got depth and the players in the squad are good enough.
"To be fair we haven't had a full strength side for a long time, but they are still doing well and pulling out the results."
