Charlton Athletic are said to be interested in signing Crewe Alexandra's Charlie Kirk on Deadline Day, with Sky Sports reporting that the Addicks have made a £500,000 bid for the 23-year-old. 

Usually operating on the left flank this season for the Railwaymen, Kirk has been one of the club's star performers in League One this term and has contributed heavily to their upturn in form under David Artell in recent weeks.

Now it appears that the third tier outfit could have a decision to make over one of their star men as they mull over the offer that has been put forward by Lee Bowyer and co this morning.

Aneke? Williams? – Can you name which Charlton Athletic player scored each these 15 goals this season?

Here, we take a look at ONE winner and ONE loser at Charlton Athletic if manage to sign Charlie Kirk today...

Winner 

Andrew Shinnie 

The main winner of this agreement being struck would be Andrew Shinnie, with the Scot having had to stand in on the right wing in recent weeks.

Signing Kirk should see the 31-year-old move back into his favoured central position under Bowyer in the long-term.

Capable of playing in numerous positions across midfield, Shinnie is far more comfortable at playing centrally as it allows his to utilise his range of passing to greater effect.

A move for Kirk would also help to fill the void that has been left by the injury to Marcus Maddison.

Loser

Marcus Maddison 

The former Hull City and Peterborough United winger would surely be negatively affected by this move and would likely be the main loser if a deal went through for Kirk.

Having largely struggled for fitness during his stint with the Addicks, Maddison once again finds himself on the sidelines, thus leaving Kirk with an opportunity to make the spot of the right hand side of midfield his own if he arrives at the Valley.

With his contract expiring at the end of the current season, the experienced winger really does has a fight on his hands to convince his manager that he is worthy of new terms.

The signing of Kirk could have serious ramifications for the 27-year-old's future in South London.
