During his first press conference as an Ajax player, Henderson said: "When I knew it could be happening [the move to Ajax] I was looking at the squad numbers to see what was available and I saw that 14 wasn't available. Initially I thought 'ooh, it's free' so I was speaking to my friend and as I was speaking I was like: 'I'm sure that's Cruyff's number'. Then he's gone: 'is it not retired?'. I've gone 'I think it might be'. Then we Googled it, [saw it was] retired, and it made sense.
"I was getting excited for a little bit, I thought it was meant to be but it quickly changed. Obviously that makes total sense. I'm not bothered about numbers, 14 was a big number for me at Liverpool but I've had different numbers throughout my career when I was at Sunderland and Coventry. It wasn't a big thing for me and I think the club wanted me to have No.6 and that fit perfectly. My son's birthday is on the 6th and my father when he played when he was younger said he was No.6 so that's nice as well."
