Henderson said: Obviously, firstly, I'm devastated for my mate Sam.
For me, personally, it's nice to be back out there. Obviously that's where I want to be. I've had a really difficult year everyone knows that through injuries, getting going, not quite getting going I just want to play football and enjoy it, with a smile on my face.
Any point away in the Premier League is obviously a good point. I thought we maybe deserved more maybe if that (last-minute corner) goes (off the) post and in on another day but I thought the lads played really well in spells.
We've just got to get that consistency throughout the game. We're showing good signs of improvement.
(We wanted) to get the next goal and put the game to bed, but obviously we couldn't do that. We missed some chances, they hit us with the sucker punch, and I thought we played some really good stuff after that. It was a bit of basketball it went either way at the end but we did alright."
On new manager Oliver Glasner, Henderson also told the club's website: I think we're showing signs of improvement weekly, so we've just got to keep doing that, keep trusting the gaffer's messages, and I believe we'll do well."
