Unai Emery has warned Aaron Ramsey not to let his contract standoff with Arsenal affect his performances.
The midfielder has spent over a decade at the Emirates Stadium but only has a year remaining on his current deal.
Ramsey is yet to hold down a role in the new manager's starting lineup and was dropped for the Premier League meeting with Chelsea last weekend.
"I spoke with him last week," Emery told reporters at Friday's press conference ahead of the meeting with West Ham United.
"I said: 'I want you focused only on training and only on the match, you show us the capacity to help the team.'
"The contract is another thing for his agent and the club but we want and I need his focus only on training, only on the match and on his performance each day."
The 27-year-old has been linked with Manchester United and Chelsea, who are said to hold an interest in the playmaker.
