Crystal Palace require a goalkeeper, central defender and striker if they want to move on to the next level.
Alan Pardew has already been backed with funds since taking charge at Crystal Palace and it is likely that he will spend big to enhance his squad again in the summer.
The former Newcastle boss has helped Palace climb up the table and their future at the top level no longer appears in doubt, but if they want to keep improving then there are areas of their squad that need to be improved.
Palace are likely to be looking for a new goalkeeper, a centre-back and a striker in the summer transfer window and all three additions could be crucial.
Although Julian Speroni remains a fans' favourite at Selhurst Park, there are concerns over whether he has the ability to be a regular in a team who want a place amongst the Premier League's elite.
The Argentine is a fantastic shot-stopper, but he is also fairly error-prone and there are better out there, if Palace are wiling spend.
The addition of a centre-back could be the most crucial one that Palace make, though, and Pardew is likely to make this his priority in the next transfer window.
Although Scott Dann looks an accomplished performer and an established starter in Palace's squad, finding a regular partner for him will be important.
The likes of Brede Hangeland, Damien Delaney and Adrian Mariappa have all been utilised by the Eagles this term, but none are quite up to standard for a side with Palace's ambitions.
The signing of a young but talented centre-back would go a long way at Selhurst Park and Pardew will already be eyeing up potential candidates to help him strengthen his defensive ranks.
He may also be keeping tabs on strikers who can help the side progress. Pardew has already brought in a number of attacking additions, but he has failed to find a reliable goalscorer.
The likes of Glenn Murray, Dwight Gayle and Frazier Campbell have all shown their ability in patches throughout the season, but a more proven goalscorer could be required if Palace are to increase their offensive threat.
The Eagles have one of the most dangerous forward line-ups in the Premier League - with Yannick Bolasie, Jason Puncheon and Wilfried Zaha all able to play behind the striker - but they need someone to put the finishing touches on their attacking moves.
If Pardew does manage to make these three additions then Palace could become one of the most dangerous and entertaining teams in the Premier League and their forward momentum would only increase.
