Sissoko became the fifth Frenchman to sign for Newcastle during the January transfer window. The 23-year-old joined from Toulouse for an undisclosed fee, and signed a six-and-a-half-year deal. After making his debut against Aston Villa, Alan Pardew said Sissoko was a 'key factor' in the victory.
Kevin Mbabu - January 31
Newcastle boss Alan Pardew had said the club's January business was finished, but there was always time for one more. Swiss defender Kevin Mbabu completed his move to St James' Park from Servette for an undisclosed fee. The 17-year-old had been on trial with the Magpies and signed a three-and-a-half-year deal. The Switzerland Under-19 international made just one first team appearance for his previous club.

The 27-year-old signed a three-and-a-half-year deal at the Stadium of Light. Born in Gateshead, Graham is a boyhood fan of Newcastle United, and he has played for other North East clubs before. He began his career with Middlesbrough and spent time on loan at Darlington.

Former Newcastle United winger Kieron Dyer signed for Middlesbrough on a short-term deal after being released by Queens Park Rangers in early January. The 34-year-old has been training with Boro and could now make his debut against boyhood club Ipswich Town this weekend. Dyer made more than 190 appearances in eight seasons at St James' Park.
Demba Ba - January 4
Newcastle's top-scorer Demba Ba joined Champions League winners Chelsea for an undisclosed fee after the London club triggered a £7 million release clause in his Magpies contract. The Senegal international made his debut in Chelsea's FA Cup Third Round win over Southampton and scored twice.
Xisco - January 31
Spanish striker Xisco joined Newcastle in September 2008 under then manager Kevin Keegan for a fee of around £5.7 million.
