Saturday lunchtime sees Newcastle welcome unbeaten league leaders Chelsea to St James’ Park for a 12.45pm kick-off. Jose Mourinho’s side have yet to taste defeat in the Premier League and have opened up a six-point cushion at the top of the table. However, Chelsea’s last two visits to St James’ Park in the league have seen them leave empty handed, with Yoan Gouffran and now-Chelsea player Loic Remy scoring against the Blues in this fixture last season to give Newcastle the win. Alan Pardew’s injury worries have been almost insurmountable in recent weeks but the Magpies boss should be boosted tomorrow. Fabricio Coloccini may return from a calf injury that has kept him out of the last three games, while 18-year-old winger Rolando Aarons is also fit. Moussa Sissoko and Jack Colback served their one-match suspensions against Burnley on Tuesday night and are once again available but Ryan Taylor, Siem de Jong, Davide Santon and Gabriel Obertan are all out. Mike Williamson was withdrawn at half-time at Turf Moor and may miss out but Sammy Ameobi is fine after making way for Remy Cabella at the same time. Frenchman Cabella is likely to start after providing the spark that lead to Newcastle’s second half comeback against Burnley, while Papiss Cisse will be involved despite revealing this week that he is still receiving attention after his dislocated knee injury back in March. As for Chelsea, defensive midfielder Nemanja Matic is suspended after picking up a fifth booking of the season against Spurs on Wednesday but star striker Diego Costa is back after serving a similar ban. Gary Cahill is doubtful after a head injury curtailed his involvement against Tottenham, while Loic Remy is pushing for a start after scoring six minutes after coming off the bench. A win for Newcastle could take them seventh in the league ahead of the 3pm kick-offs, while a Chelsea victory would send them nine points clear of Manchester City.
