Henry and Napa arent centre forwards, so what makes you think this is the answer?
Now isnt a time for trying radical changes in system, its about going back to basics and grinding out enough points to ensure League 1 football next season.
We arent in a position to check players in who may not yet be ready for first team football (id argue those that havent been included yet arent, otherwise why havent they been, remember Napa has) or for players learning how to play in a new position.
What we need now, is to go back to basics, play people in positions they know well and are experienced in, yes Thomas was poor today but he has shown that when fit and we create chances, that he can score goals, i know who id rather through on goal needing a last minute winner to stay up and its not some lad from the youth team no matter how good they may go onto be.
Thomas will score if we create, despite his numerous faults, its not just down to him if he doesnt score.
Obika is useful if he has a partner or midfield players joining in/getting beyond him....if we dont do these things he cant be expected to hold onto the ball indefinetely.
There is plenty to work on, as there has been all season, but the players do have enough about them to get the required points if they apply themselves correctly (particularly at set pieces) and make good decisions, neither of those happened today and we lost the game because of it
