The Hammers will take on their North London rivals at White Hart Lane in the Premier League on Sunday.
“If you put San Miguel on the back then it looks like you don’t have a serious name to play football,” the 28-year-old Spaniard, whose full name is Adrian San Miguel del Castillo, told The Mirror.
“Everyone knows San Miguel for the beer. I like my surname but Adrian is my name on the pitch and on my shirt.
“I can promise that if we beat Tottenham – and it will be a difficult game because they are playing well at home – then I will buy San Miguel for everyone.”
West Ham will head into Sunday’s London derby at White Hart Lane on the back of a 1-1 draw with Everton.
Slaven Bilic’s have not won in their last two league games, but they have lost only one of their last nine league matches.
West Ham are sixth in the Premier League table at the moment with 21 points from 12 matches, level on points with fifth-place Tottenham and just three points behind Manchester United, who occupy the fourth and final Champions League spot.
The London outfit have scored 23 goals, conceded 16 goals and created 125 chances in 12 Premier League games so far this season.
