Derby County will hope that they can keep hold of Louie Sibley after Friday's domestic deadline following interest from Leeds United.

The attacking midfielder was a real breakthrough star for the Rams last season after scoring five goals in 11 Championship games and he impressed with his overall game.

So much so, it has been reported that the Whites want to bring the 19-year-old to the Premier League and it has been claimed a £10m fee could be enough to seal the deal.

Whether that materialises before the window shuts remains to be seen but losing Sibley would be a bitter blow for Phillip Cocu who will want to strengthen, not weaken, his squad this week.

Further new signings will be needed

As touched upon, Derby's squad already looks short in the final third and if Sibley departs their need for attacking additions will increase significantly.

They aren't in a position to lose an attacking player and the teenager has shown he is a major goal threat since he started playing for the first team. With two days to go, finding replacements would be almost impossible, so it would leave Cocu in a very difficult position.

The mood around the club will turn negative

Whilst Derby and Leeds will never be each others biggest rival, there's no point pretending they get on, particularly after what's happened in recent years.

So, losing Sibley to the Yorkshire club would hurt. It would send out completely the wrong message for a club that wants to win promotion and it create a negativity around the club that would be very hard to shift.

Of course, if a stupid fee was offered it would be understandable but £10m certainly doesn't fall into that category.
