Charlton Athletic boss Jose Riga says they're aware Diego Poyet's current deal will expire in June.
Arsenal and Tottenham are chasing the midfielder.
Riga told the South London Press: "Be sure that we have our eyes very opened about this.
"I think he is happy at the minute. He can be a very good player. I'm sure with the environment and family he will always receive good advice.
"It is the same for Diego as it is the team - the way is still long."
