We're already more than a week into the January transfer window, and not surprisingly, the rumour mill is now well into full flow, with any number of clubs linked with any number of players.

One side who have so far yet to add to their squad is Preston North End, although it would be no surprise if this was to change sooner rather than later.

The Deepdale club currently sit tenth in the Championship, and with just two points separating them from the play-offs places, they will still be harbouring hopes of promotion this season.

If they are to pull that off however, Preston will surely have to perform well in the January transfer window, as there are areas of his squad manager Alex Neil will surely want to strengthen if they are to secure a place in the top-flight.

Here, we take a look at three deals that would help make this a perfect January transfer window for Preston.

Scott Sinclair

One deal that already looks close to completion is the signing of Scott Sinclair from Celtic, with reports claiming that the winger completed his medical ahead of the proposed move on Tuesday afternoon.

Having previously won promotion from this level with Swansea, and with three consecutive domestic trebles in the bag from his time with Celtic, Sinclair certainly has that winning mindset that could help Preston keep themselves in the fight for promotion until the end of the season at the very least.

Indeed, with the quality of delivery and eye for goal he possesses, Sinclair's ability could be just as important as his experience for Preston in the coming months.

Ivan Toney

Once they have secured Sinclair to supply the chances, Preston will need an attacker to finish them.

Centre forward has been something of a problem this season for Alex Neil's side, with a season-ending injury suffered by Louis Moult late in August leaving Jayden Stockley and David Nugent as the club's only two options in that position.

The pair have scored just three league goals between them this season, which simply doesn't feel like enough, meaning adding another option in that position looks vital for North End.

One forward who has been linked is Peterborough's Ivan Toney, who has been in prolific form Posh over the past 18 months, scoring 40 goals in 85 appearances in all competitions, which certainly suggests he can offer the goalscoring touch North End are looking for.

Keeping hold of Ben Davies

What will surely be just as important to bringing in new signings for Preston, is keeping hold of the key players they already have, and perhaps none more so than Ben Davies.

The 24-year-old has been a key figure at the heart of Preston's defence this season, and it is unlikely to be a coincidence that their recent dip in form that has taken them out of the top six has rather coincided with the injury problems suffered by Davies.

There were reports earlier in the season of interest in the centre back from a number of top-flight clubs, including Newcastle, Everton, Wolves and Brighton, so securing a new contract for Davies now would be a firm 'hands off' warning to those sides, while also lifting any pressure there may be on North End to sell him in the summer, when there will be just one year remaining on his current contract at Deepdale.
