It's fair to say his role this season is hardly "major".... But players of his calibre make the difference when really needed and least expected. Drogba last season had a minor role compared to his usual seasons, but his performances had a major impact in qualifying for the knock-outs of the CL and eventually winning it. Expect Lamps' performances this season (no matter how minor his role is) to make sure we finish top 3. England yesterday was just an example, and as Rooney admitted he's been doing this throughout his career. You're right, we might not sacrifice too much if he leaves, but can you tell me we can't do with Drogba this season, for example? His experience will always be useful in one way or another.
