The transfer window closed on Monday evening to leave the club going into February with seven deals done as the squad prepare for the second half of the season.
During the final hours of the window the club were able to announce that Wilfried Zaha had made his loan move permanent, arriving home on a five and a half year contract.
The start of the month saw Alan Pardew make his first signing as Yaya Sanogo arrived from Arsenal on loan until the end of the season.
The French under-21 striker told the official website "When the Arsenal manager spoke with me about Crystal Palace I was very happy because I want to play more games. I think Palace are a good team, I watched the game against Tottenham and it was a great performance from the guys. I hope I can help the club have a successful second half of the season.”
Next in was 23 year-old midfielder Jordon Mutch from Queens Park Rangers on a four and a half year contract for an undisclosed fee. He made his debut in the home game against Everton.
Speaking to Palace TV on the day of signing he commented, "I wasn't getting too much game time at Queens Park Rangers and I wanted to play football and Palace gave me the opportunity to do that. It's a great club with a great manager and the fans are great too so I was over the moon to come here and I'm delighted it's done."
Last Thursday afternoon saw the next new signing through the door at Beckenham Training Ground when striker Shola Ameobi joined on a free transfer.
The Nigerian international has signed a short-term deal with the Eagles until the end of the season and was a free agent after leaving Turkish side Gaziantep last month.
“I'm very excited to be here, I wanted to get back in the Premier League and having worked with the manager before it's been great to come back and hopefully help us avoid the relegation battle,” he said.
“I had a couple of other clubs interested but I think my relationship with Alan [Pardew] and how much I enjoyed working with him was one of the big factors in my decision.
“He instills confidence in players and he always seems to get the best out of them, certainly he did that at Newcastle and hopefully he can do that for me and the rest of the lads here.”
Into the last two days of the window we went and on Sunday the club were able to confirm the signing of Senegalese international left-back Pape Souare from Lille on a three and a half year contract for an undisclosed fee, subject to a work permit being received.
The 24 year old defender is a product of Lille's academy and made 55 league appearances for them, helping them win a league and cup double in 2010/11 and featuring for the club in the UEFA Champions League and Europa League in recent seasons. He also had a season-long loan spell with Stade Reims in 2012/13.
Pape has won five caps for Senegal, including two in this month's Africa Cup of Nations competition in Equatorial Guinea. He also featured for his country's under-23 side in the 2012 Olympics.
Onto deadline day and apart from Zaha rejoining the club, we welcomed Barton Rovers striker Keshi Anderson and Lee Chung-Yong from Bolton Wanderers.
Keshi scored a six minute hat-trick against us for Brentford's U21 Professional Development League Two side last week and has 16 goals to his name for Barton in the Southern League Division One Central this season.
The South Korean international, Lee Chung-Yong, signed a deal through until June 2018 for an undisclosed fee.
He joined Bolton in 2009 from FC Seoul, where he made his debut at the age of 18. He went on to play 195 times for the Trotters, scoring 20 goals, and has three in 26 outings so far this season.
Lee has also represented his country in two World Cups, scoring twice in the 2010 competition. He was also won his 65th cap for Korea in their opening game of the Asian Cup last month.
