Chelsea may be the subject of a transfer raid from Premier League rivals Newcastle United.
The Magpies are said to have been scouting Blues players over the past few months.
Per Chronicle Live, the Magpies had scouts watching their 4-3 win over Manchester United.
Chelsea midfielder Conor Gallagher was the player they were focusing on the most.
Newcastle did sign Lewis Hall from Chelsea last summer in a loan deal that will be made permanent this summer.
Gallagher is not eager to leave Chelsea, but may be forced to go by the club to raise transfer funds.
