Newcastle United manager Alan Pardew is aiming to bring in "four or five" new signings if his in-form side qualifies for Europe.
Newcastle are currently sixth in the Premier League, just three points off the Champions League places, and are amongst the favourites to land a Europa League spot.
Pardew had planned to add another two players in the summer regardless of where his side finish, but asked whether European qualification would require a bigger recruitment drive, Pardew told The Sun: "It will change us a little bit.
"I think we would need a bigger squad, therefore where we might only bring in two or three we might need four or five to bolster the numbers.
"We'll have to see because obviously we've got contracts up here as well, whether we all agree to stay or they go as well. We'll have to wait and see."
Pardew's recruits in the summer of 2011 - such as Yohan Cabaye, Demba Ba and Hatem Ben Arfa - have all been big hits in the Premier League this season and January signing Papiss Demba Cisse has scored nine goals in eight games to keep the Magpies flying high.
The Toon are hoping to attract the same calibre of player this summer, with Netherlands defender Erik Pieters, France right-back Mathieu Debuchy and FC Twente centre-back Douglas all reportedly on their wanted list.
Newcastle manager Pardew is also eager to keep hold of all his star performers and has warned any player looking to join a "bigger'' club to think twice.
Andy Carroll and Jose Enrique, who both left Tyneside for Liverpool, were taunted by Magpies fans on their return last Sunday as their former club secured a 2-0 win which took them 11 points clear of the Reds in the Premier League table.
That gap became 13 points over the weekend after Kenny Dalglish's men were only able to manage a home draw with Aston Villa while Newcastle won 2-0 at Swansea.
Writing in his programme notes ahead of Monday's home clash with struggling Bolton, Pardew said: "I took no satisfaction from seeing our former players Andy and Jose enduring a difficult day as they were fantastic for us during their time at this club.
"But maybe this season has changed a few perceptions and sent out a message to players tempted by offers to join so-called bigger clubs in the Premier League.
"Newcastle have proved time and again over the last few months that we can compete with big-name clubs like Liverpool, and maybe it will encourage players to think again if they dare to believe the grass is greener elsewhere.''
