Derby County have lost their fight to keep Archie Brown at Pride Park his summer.

What's the talk?

That's according to a statement posted on the FC Lausanne-Sport website, with the Swiss Super League side confirming that the 19-year-old has joined their club after leaving the Rams upon the expiry of his contract.

In the Rams' retained list published earlier this month, the Championship side revealed that the left-back was one of only two U23 players to be offered a new deal at Pride Park this summer, ultimately meaning that Brown turned the club down in favour of a move to Switzerland.

Rooney will be livid

Considering just how difficult it appears it will be for Wayne Rooney to sign players this summer, with it being reported that the Rams were being financially outmuscled in a deal for George Edmundson by recently promoted League One side Peterborough United, as well as being under a transfer embargo due to the club's ongoing sale and general poor finances, the fact that even a youth player Derby have offered contracts to is uninterested in staying on at the club is sure to leave Rooney livid.

Indeed, at present, Rooney has just 15 first-team squad members signed up for next season, meaning that the 35-year-old will almost certainly have to promote from the club's U18 and U23 sides, as well as bringing a number of players to the club on free transfers and loan deals, in order to simply be able to put a team out next term, let alone one that is capable of surviving relegation.

However, if things continue the way they have been going in recent weeks and months, with the departure of Brown being the latest disappointment for Rooney to endure, things are certainly looking pretty bleak regarding the future of Derby County at present.
