Paris Saint-Germain, Inter Milan and Real Madrid have been monitoring Jesse Lingard.
Lingard has played exceptionally well since joining West Ham on loan from Manchester United. Lingard has scored eight goals in nine matches.
West Ham are keen to sign Lingard permanently at the end of the season.
Lingard has yet to make a decision about his future but he would like to play in the Champions League next season.
