Police are investigating claims that West Ham supporters threw coins at Frank Lampard following his 200th goal for Chelsea at the weekend.
In a statement, West Ham said:
"West Ham United will be working with Chelsea to investigate the reports of missile throwing during Sunday's game at Stamford Bridge.
Any individual found to have acted in an inappropriate way will have to face the consequences of their actions, including the possibility of a ban from attending future matches."

Publishers Little Brown say the first installment in the series, Frankie versus the Pirate Pillagers, will hit bookshops in June this year.
Two more titles, Frankie versus the Rowdy Romans and Frankie versus the Mummy’s Menace are scheduled for 2013, with a further two slated for early 2014.
Editorial Director Samantha Smith said:
"It's crucial to get kids excited about reading at an early age and Frank's vision for a series about friendship, football and fun will do just that. We think it’s brilliant and we're sure readers - and parents - will agree."
Footballer Frank Lampard has signed a new deal - but unfortunately for Chelsea fans it is with a publisher to write children's books.
The midfielder is writing a series of five stories, based on the adventures of a school boy, his football-loving friends, and pet dog Max. Aimed at children aged five and over, the series with publishers Little Brown will be called "Frankie's Magic Football".
Lampard said the characters were "loosely based on friends and team mates" he's played with over the years.
He said: "I first had the idea of Frankie and his Magic Football when reading stories to my own children. Sport and reading are two essentials for us at home, so I decided to make up my own football stories and adventures."
Lampard is not the first footballer to turn author - Arsenal star Theo Walcott has written a series of children's books and former England manager, Terry Venables, co-wrote a series of crime novels.
