The Premier League club have in recent seasons built up a battalion of young players who are then sent out on loan.
The vast majority will never have a Chelsea career but can bring in a profit later down the line, as long as they were bought cheaply enough to begin with.
On Tuesday night, according to A Bola, Chelsea had a scout watch Portugal’s U21 side beat their counterparts from Greece 1-0.
A Bola call the scouts attending the match ‘sharks’ as they look to snap up young talent before players become much more widely known, and therefore much harder and more expensive, to buy.
There were several excellent young Portuguese talents on show including Ruben Neves, Goncalo Guedes and Diogo Jota.
