Chelsea have had a £73m offer for Sporting Lisbon striker Viktor Gyokeres rejected, according to reports.
Mauricio Pochettino's men have struggled in front of goal this term, with their 35 goals in 21 league games making them the third-lowest scorers in the top half of the Premier League.
They have been linked with bringing in a striker this month - despite spending over £1bn over the past three transfer windows under Todd Boehly - with Ivan Toney and Victor Osimhen emerging as potential targets.
However, they now appear to have turned their attention to Gyokeres, only to have an €85m (£73m) bid knocked back by Sporting, as reported by Portuguese outlet Record.
