Sam Allardyce will be hoping that the signings he makes during this window can make their way into Crystal Palace's top five in future.
As the January transfer window approaches the halfway mark, HITC Sport is taking a look at the five best signings that Crystal Palace have made since the start of the Premier League era in 1992...
5. Yannick Bolasie
While other players have made greater contributions during their time with Crystal Palace, Yannick Bolasie sneaks onto the list due to the incredible profit that the Eagles went on to make by signing him. After landing the winger for £350,000 in 2012 (via Mirror), he went on to help the side reach the top flight and stay there for a number of years before departing for Everton last summer for £25 million (via BBC Sport).
4. Dougie Freedman
Though he boasted a better strike-rate during his first spell at the club, there is no question that Dougie Freedman's second spell was hugely significant. It was his goal in the dying minutes on the final day that kept the Eagles in the second tier in 2001 and he played his part as they secured promotion in 2004.
3. Mile Jedinak
Before his departure for Aston Villa last summer, Mile Jedinak was an important member of the Crystal Palace dressing room. Under his leadership, the Eagles secured promotion to the Premier League, and he remained a stalwart of the team for several years in the top flight.
2. Andrew Johnson
After an unspectacular spell at Birmingham, few would have expected that Andrew Johnson would go on to become one of the more impressive English strikers in the game during his spell at Crystal Palace. His 27 goals inspired their promotion push in 2004, and he followed that up with 21 strikes in the top flight. The fact that Everton ultimately ended up paying £8.6 million (via BBC Sport) for him in 2006 confirmed what an excellent piece of business they had done when they initially signed him, especially as their chances of getting a bigger fee were probably harmed by them remaining in the second tier.
1. Julian Speroni
Julian Speroni got off to a poor start at Crystal Palace, but it is safe to say that that has long been forgotten about amongst the Selhurst Park faithful. He has won their Player of the Year award four times, and has made over 350 league appearances. His consistency was key to their most recent promotion and their ability to remain in the Premier League, and it is not difficult to imagine that the keepers ahead of him in the current pecking order are maintaining their own form because the 37-year-old continues to push for a chance.
