Input: Question: Of the athletes Davide Santon assisted for goals against Chelsea, which one has been playing longer? Passage:On 30 August 2011, Santon signed for English club Newcastle United on a five-year contract, for an undisclosed fee; according to Inter, Santon was sold for €4 million. He made his Newcastle debut on 16 October 2011 as a second-half substitute against Tottenham Hotspur. He went on to make his first Premier League start for the club in December away against Norwich City, before making his full home debut the next week against Swansea City. He set up Papiss Cissé's first goal in the Magpies' shock win at Chelsea in the 19th minute. Halfway through the 2012–13 season, Santon was the only Newcastle player to have started every Premier League match. In the 3–2 win over Chelsea on 2 February 2013, he assisted the first goal with a cross for Jonás Gutiérrez, and the winning goal scored by Moussa Sissoko. He scored his first goal for Newcastle on 17 March, an equaliser against Wigan Athletic.
