Di Resta to replace Schumacher?

Mercedes CEO Nick Fry has said that Paul di Resta would  be one of the drivers that the team would consider to replace Michael Schumacher.
Schumacher has had a poor season so far, scoring just two points.
Paul di Resta has scored 13 more points than Michael Schumacher so far this season.
With Schumacher only having finished two races this season and yet to cross the line higher than tenth, Fry admitted an upturn in fortunes was likely to be needed in order for him to continue racing.
