West Ham boss Julen Lopetegui refused to be drawn on potential new signings amid the club's pursuit of Aston Villa striker Jhon Duran.
The Hammers had a bid of £32million plus academy product Lewis Orford rejected earlier this week but Duran remains a top target for the club.
Lopetegui is in day-to-day contact with sporting director Tim Steidten, who is leading on transfers and was spotted taking several calls during the team's open training session in Jacksonville Florida on Friday, but the manager insisted his focus is only on his current players.
