Player Valuation: £150m
I dont see 'off the bench' as a negative in a pretty strong squad...especially given the attacking options we have.But as you have pointed out, Martinez doesn't consider the bench as a negative, he loves changing his wingers towards the end of a game and has often done the same for the number 10 role Barkley/Osman/Naismith - the only reason he hasn't done it with the striker postion imo is that we haven't had any options.
Whilst Barkley is out I can easily see him rotating his starts for Lukaku and Eto'o in the striker position and switching them after 60mins and the same for behind the striker for Naismith, Osman and Eto'o. If Eto'o comes on as a sub as effectively as Aguero has done plus a few starts as well, I doubt he'll be unhappy.
However, there is a prestige in starting games that players like to enjoy. I tend to believe Martinez wont want to ruffle any feathers with players like Lukaku (who, tbf, he's paid £28M for and is therefore unlikely to want to bench too often) and Eto'o (who he's obviously in awe of). It's inevitable that out of the three Naismith will lose out more often than not.
