Gera believes the next three games - Sunderland and Swansea away and home to Stoke - will provide a stern test for the fourth-placed Baggies.
The Hungary international said: "Normally against Chelsea and the bigger clubs you have no pressure. These games coming up will be different.
"They will be a big test. But we are confident we can get results from them and I'm not surprised how well we've done. We're a massive team now."
