Yeah that’s not true at all really.
Chelsea have actually made a complete hash of things in recent years losing Lamptey, Guehi, Liveramento, Tomori and Tammy as they thought they weren’t good enough.
Instead they threw away millions on various fixes which still haven’t worked out.
Not such which other clubs have fantastic success stories from loans? Liverpool have only really embedded Trent in their team (and he’s not that great really), City have Foden, Arsenal Saka and Spurs Kane.
United are currently having some success this season with Hannibal, Laird, Fernandes and to a lesser degree Diallo. All in the Championship. Dalot has also took his chance following his loan in Milan whilst the likes of Rashford, Mctominay and Elanga have all embedded themselves in and around the first team.
