The young striker has been recalled from his loan with Scunthorpe United.
Sears told whufc.com: "I got the call to report back and I spoke to Grovesy and he said to come back and start training on Wednesday. It's good to be back and to come home.
"Obviously, my loan was up on 3 January so I wasn't expecting to come back before then as I had three or four games left. I'm happy, in a way, to come home and be back at West Ham. Staying in a hotel at Christmas time isn't the best, so it's nice to be back where I come from.
"It's a massive period for the lads, for the team and for everyone. We have four games in a short period of about eight days so hopefully there will be a chance for players who haven't been playing to play and, you never know, I might get a go. I'll just have to see what happens.
"You see what's happening and the table isn't really doing us any favours at the moment, but the lads are all confident that we'll turn it around and hopefully we can. You can tell on the training pitch that we can.
"The last two games have been called-off, which has been frustrating, but if I'm called upon at Fulham then I'm sure I'll be ready."
