England head coach Stuart Lancaster has called 34 of his players to train at their Pennyhill Park base ahead of their final Six Nations clash with France on Saturday.

Lancaster's side earned their third win of the championship with a 25-13 victory over Scotland in last weekend's Calcutta Cup clash at Twickenham which, coupled with Wales' win against Ireland, pits them in a predominantly three-horse race for the title.

However, Lancaster was left frustrated with several try-scoring opportunities squandered by his players during the triumph over the Scots. With this year's Rugby World Cup fast approaching, Lancaster is taking all the time available to assess his squad and the players available to him - including Bath's cross-code star Sam Burgess.

Wales and Ireland remain England's strongest contenders in the fight for this year's championship, although France could still mathematically win the title.

England top the standings with a points difference of plus 37, with Ireland on plus 33 and Wales on plus 12 - all have recorded three wins . France currently have two victories, having beaten Italy 29-0 in Rome on Sunday, and could overhaul the rest should they win and other results go their way.

England play France in Saturday's final match at 5pm, with Wales facing Italy in Rome at 12.30pm and Scotland hosting Ireland at 2.30pm.
