West Ham United and Fulham have reportedly identified Philadelphia Union defender Kai Wagner as a potential target.
Although the two clubs enjoyed contrasting summers in the transfer market, the majority of Premier League teams will be eyeing bargains at the start of 2021.
According to the Daily Mail, the London outfits are monitoring the development of Wagner, who has been impressing in the MLS.
The left-back has contributed one goal and eight assists from his 49 outings in the United States, while he has previously featured for Schalke 04's second side.
The report suggests that the 23-year-old may be available in January for a fee in the region of £3.5m.
