The 27-year-old Colombian joined the Hammers in January on a contract until the end of the season.
"Firstly, I think of West Ham and give the maximum result here," Armero told the Newham Recorder. "It is normal that as we are getting close to the World Cup, I like to keep pace and be in full capacity.
"I would like to have a good end so in the future have a new contract with the team."
Armero has made three appearances for West Ham since arriving at Upton Park at the start of the year.
