Pardew says the 22-year-old will not burst on the scene at St James' Park like Papiss Cisse.
Amalfitano joined the Magpies from Stade de Reims this summer but he did not feature regularly for the Ligue 2 champions, and may be short of fitness
Alan Pardew: "Romain's a player who has been off the radar for a while, so it's going to take him some time to get back to his very, very best.
"However, he is coming into a great environment and I'm sure he'll settle very quickly.
"I hope the fans don't expect him to burst on the scene like Papiss (Cisse) did last season.
"We will take our time with him, and the players will make him feel at home.
"That's the beauty of the French market.
"He plays across the midfield, a bit like Sylvain Marveaux.
"Word of mouth is very good and there's a lot of contact from players wanting to come to this club.
"That arms me for the Europa League and it may well help me to bring players in and out."EURO 2012 GROUP STAGES Friday June 8 Warsaw, Group A: Poland v Greece (1700) Wroclaw, Group A: Russia v Czech Republic (1945) Saturday June 9 Kharkiv, Group B: Holland v Denmark (1700) Lviv, Group B: Germany v Portugal (1945) Sunday June 10 Gdansk, Group C: Spain v Italy (1700) Poznan, Group C: Republic of Ireland v Croatia (1945) Monday June 11 Donetsk, Group D: France v England (1700) Kiev, Group D: Ukraine v Sweden (1945) Tuesday June 12 Wroclaw, Group A: Greece v Czech Republic (1700) Warsaw, Group A: Poland v Russia (1945) Wednesday June 13 Lviv, Group B: Denmark v Portugal (1700) Kharkiv, Group B: Holland v Germany (1945) Thursday June 14 Poznan, Group C: Italy v Croatia (1700) Gdansk, Group C: Spain v Republic of Ireland (1945) Friday June 15 Donetsk, Group D: Ukraine v France (1700) Kiev, Group D: Sweden v England (1945) Saturday June 16 Wroclaw, Group A: Czech Republic v Poland (1945) Warsaw, Group A: Greece v Russia (1945) Sunday June 17 Kharkiv, Group B: Portugal v Holland (1945) Lviv, Group B: Denmark v Germany (1945) Monday June 18 Gdansk, Group C: Croatia v Spain (1945) Poznan, Group C: Italy v Republic of Ireland (1945) Tuesday June 19 Donetsk, Group D: England v Ukraine (1945) Kiev, Group D: Sweden v France (1945) QUARTER-FINALS Thursday June 21 Warsaw, QF1: Winner A v Runner-up B (1945) Friday June 22 Gdansk, QF2: Winner B v Runner-up A (1945) Saturday June 23 Donetsk, QF3: Winner C v Runner-up D (1945) Sunday June 24 Kiev, QF4: Winner D v Runner-up C (1945) SEMI-FINALS Wednesday June 27 Donetsk, SF1: Winner QF1 v Winner QF3 (1945) Thursday June 28 Warsaw, SF2: Winner QF2 v Winner QF4 (1945) FINAL Sunday July 1 Kiev: Winner SF1 v Winner SF2 (1945)
