England interim coach Stuart Lancaster has been warned that his team\'s impressive Six Nations victory over France will not necessarily mean that he is guaranteed to land the job full-time. Lancaster\'s youthful side earned critical plaudits on Sunday after a stirring 24-22 win over the French in Paris, the first time ever England have won three away games in the Six Nations. The win led to calls for Rugby Football Union chiefs to install Lancaster as England coach on a permanent basis, with South African Nick Mallett believed to be his main rival for the post. However RFU chief Ian Ritchie warned that while Lancaster\'s application had been strengthened by results in the Six Nations, other factors would be taken into consideration when applicants for the job were being considered. \"Stuart has been doing a fantastic job and this was a great result, it is a helpful thing to strengthen his case,\" Ritchie said. \"We are going through a process. It is not going to be based on what happens in the Six Nations alone -- whether we had lost to France, whether we had won or what happens against Ireland next weekend. \"We are going through a proper process to try and find the best possible candidate. \"Winning here in Paris, fantastic though it is and a great win, does not change what we will go through. \"I am of the view we have a great list of people interested in the job and I include Stuart in that. He is putting his best foot forward but it is a comparative process.\" Several pundits including former England internationals Jeremy Guscott and Stuart Barnes have expressed scepticism about Lancaster\'s credentials, believing the RFU should opt for the greater experience of Mallett.
