How do you say thank you to a man who played over 350 games for your club, winning six Premier League titles, three FA Cups and one Champions League over nine-year spell?
Well, if you're former Manchester United boss Sir Alex Ferguson, you send them the most underwhelming message inside of your new book.
Neville was a member of the synonymous 'Class of 92' and was an important player at Old Trafford before moving to Everton in 2005.

He was a perfect utility man for Ferguson and played a great role in helping United dominate the league during that period.
So when he was handed a copy of the Scot's new book, Neville may have been expecting a heartfelt message of inspiration from his former boss.
Alas, Ferguson wrote: "To Philip, Best Wishes, Alex Ferguson." The sort of message Ferguson reels off 100 times a day at a book signing. Although, Neville seemed happy enough on Twitter.
The former United defender is still making his own way as a coach and is currently assistant manager at Valencia having left the Old Trafford backroom staff when Louis van Gaal arrived.
His former teammate Ryan Giggs is still at United and has been touted as a possible replacement for the Dutch boss when he retires at the end of next season.
While Giggs' story from academy graduate to manager would be a fairytale story, next summer could come too soon for the Welshman.
Another stint as assistant under a manager like Carlo Ancelotti, Pep Guardiola or Jose Mourinho would further enhance his chances of being successful on his own, it's just a case of whether Giggs is patient enough.
Would Ryan Giggs be a good Manchester United manager? Let us know what you think by leaving a comment below
