Peter Odwemingie pulled one back for Cardiff, who were close to snatching a point after an improved second half.
Newcastle went ahead in controversial circumstances when, seconds after Fabricio Coloccini went in two-footed on Fraizer Campbell in the penalty area, they raced away for Remy to finish past David Marshall, who had made two brilliant saves earlier but was poorly positioned.
Papiss Cisse’s toe-poked finish was well-saved by Marshall, but Remy coolly placed the loose ball inside the right-hand post for 2-0. Yohan Cabaye hit the woodwork with an excellent free-kick, and the visitors were good value for their lead going into half-time.
Cardiff were far better after the break, as half-time substitute Jordon Mutch pulled the strings in midfield. They pulled one back thanks to the youngster’s fine flick, which put Odemwingie through to score his first league goal for Cardiff.
Mutch was at the heart of Cardiff’s attempts to level but Newcastle, who were dangerous on the counter attack, held on for their third league win of the season.
Pre-match – Toon duo dropped: After poor recent performances, Hatem Ben Arfa and Mapou Yanga-Mbiwa are relegated to the bench, with Cabaye rewarded for his stunning goal against Everton with a start. Andreas Cornelius continued to miss out for Cardiff, while last week’s match-winner Mutch was kept on the bench.
17+18’ – SAVES: Marshall makes two superb saves from Remy and Moussa Sissoko to keep Newcastle at bay.
30’ – PENALTY APPEAL: Coloccini flies in two-footed on Campbell, but having got a slight touch on the ball Kevin Friend waves play on.
30’ – GOAL (Cardiff 0-1 Newcastle): As Toon counter following that penalty appeal. Remy cuts inside from the left wing before drilling a low shot past Marshall, who was caught out of position.
38 – GOAL (Cardiff 0-2 Newcastle): Remy makes it 2-0, drilling a low finish from the edge of the box after a good Marshall save from Papiss Cisse.
43’ – WOODWORK: Cabaye hits the post with an audacious free-kick from the right wing. Fantastic effort.
57’ - GOAL (Cardiff 1-2 Newcastle): Odemwingie picks his spot after a lovely first-time through ball by Mutch.
60 + 73’ – MISSES: Aaron Gunnarsson fails to convert from three yards for Cardiff, while Newcastle’s Jonas Gutierrez heads over from five.
63, 76, 79, 84’’ – SAVES: Marshall denies Sissokho and Cisse while Krul keeps out Craig Bellamy and Mutch, all excellent stops.
Remy made it five goals in five matches with his first-half double.
Cisse has now gone 13 Premier League games without a goal.
Newcastle have won their last seven matches against Cardiff
Newcastles last 11 goals have come from French players. The all-time record for a club's goal streak by foreign players was set in 2004 by Arsenal, who had French players scoring 12 consecutive goals
TALKING POINT – Should Cardiff have got a penalty? Coloccini was lucky to escape giving away a spot-kick and possibly getting sent off for a reckless challenge on Campbell just before Toon went ahead.
