The Hammers are now through to the last 16 of the Capital One Cup and Tomkins is eyeing a good run in the competition.
He told whufc.com: "We think we can do well in this competition this season. We've got a good squad here and for the players who played tonight and haven't been involved in too many first team games, it's good fitness for us.
"We're trying to fight for our places in the team and we'll keep going for it. Hopefully we'll have a bit of run in it."
