"I never used to think of myself as a target-man when I first started but I've learned to deal with it. I've tried to mould myself into one," Fletcher told the Sunderland Echo.
"I used to play off a main striker when I was at Hibernian, because I was actually quite small when I broke into the first team - although I've obviously grown a bit! But I don't mind whatever system I'm played in. I'm sure I'd adapt.
"I'm happy to play on my own up front, although I know not everyone is, but, for me, I quite like the added pressure of the extra responsibility. I quite enjoy it. But, having said that, I'm OK in any system.
"It's good to have Danny here. We've spoken with the gaffer about it and it's up to him to decide what formation he wants to play. But at least now he knows he has all sorts of options in terms of how to use me and Danny and Stephane Sessegnon.
"That's always good because not many managers have options, but I think he has them in abundance, so it's good for him and us.
"The gaffer changes things around all the time in training and five-a-sides, so we are always working on combinations of players, which means we're always working together.
"And even if Danny's on the other side, you can always watch what he's doing to pick up on how he plays. So it's all good for us as a squad."
