The France striker may have rejected the Magpies in favour of a move to Chelsea - but he helped a certain summer signing move to St James' Park.
Indeed, summer signing Remy Cabella has revealed that the former QPR striker advised him to join the Magpies during the transfer window.
Remy, of course, is now a Chelsea striker, having reportedly rejected Newcastle's advances before the transfer deadline passed.
However, the 27-year-old was one of four France players who helped persuade Cabella to make the move from Montpellier to Tyneside.
"During the World Cup I talked with French players that are playing or who have played at Newcastle, like Yohan Cabaye, Loic Remy, Mathieu Debuchy, Moussa Sissoko, and I have only heard good things about the club," Cabella told France Football.
"They made me dream. They told me, 'If you go there, you will make a very good choice.'"
Could Remy, then, have done the Magpies a huge favour in helping them capture one of their biggest transfer targets over the last few months?
The same can be said of Yohan Cabaye and Mathieu Debuchy, who have both left St James' Park but obviously hold good memories from their time working under Alan Pardew.
For Moussa Sissoko, meanwhile, the appeal of persuading Cabella to join Newcastle is obvious.
Cabella has made a significant impact since joining the Magpies, although Pardew's men struggled to find their killer instinct in the final third against Manchester City and Aston Villa.
They managed it against Crystal Palace, when they scored three times, but Neil Warnock's visitors scored three of their own to keep Newcastle winless.
Their next Premier League action sees them travel to Southampton.
