West Ham in the current season is in 7th place, now the team is not in the best shape, but still at home field "Hammers" are an extremely dangerous opponent.
Arsenal is in 3rd place, trailing Liverpool by 2 points, nominally the "Canaries" look favourites today, but the away matches the team are quite weak. And West Ham is an uncomfortable opponent for Arsenal, so expect the hosts to score today.
Prediction: both teams to score and at least 3 goals to be scored. We recommend the “BTTS - Yes + Over 2.5” bet, odds 2.15
