Firstly, Howe wasn't sacked, he quit for personal reasons.
Secondly, Howe oversaw a huge squad change and a shift in playing style at Burnley. He took over an ageing squad that included the likes of Steven Fletcher, Graham Alexander, Clarke Carlisle, Steven Caldwell, Tyrone Mears, and Kevin Long and completely recycled the team, he brought in young players like Charlie Austin, Ben Mee, Kieran Trippier, Danny Ings, Sam Vokes, Junior Stanislas and Jason Shackell who would later form the core basis of Burnleys promotion team.
Thirdly, that side got promoted the season after he left. Finally, it was almost eight years ago and he was also only 34. The same latitude we grant to young players starting their careers to make mistakes, we should grant to managers too.
What he has achieved at Bournemouth since then is nothing short of a miracle. He's spent a fraction of what everyone else has spent and got them in a position where now they're considered a steady mid-table team. He’s working with Simon Francis and Steve Cook at CB ffs! Both of them have been with him since he brought Bournemouth up from League One into the Championship, and then from the Championship up to the Premier League.
Most importantly he’s got a unique ability to actually ‘coach’ players. He’s turned bog standard league one players into disciplined Premier League players down there.
To have them where they are, on the budget he’s had, for the size of the club (less than 15,000 seater stadium) is insane. Look at the quality of the players he’s signed for tiny fees (mostly from the lower leagues), the likes of Ake (£20m) Fraser (£400k) Josh King (£3m), Callum Wilson (£3m) Brooks (£11m) Cook (£6m) Ramsdale (£800k) Mepham (£12m) and Stacey (£4m). He's made a massive profit on players like Mousset, Ritchie and Mings. He's brought through youth and players from the lower leagues and has them in a clear system, playing attractive, pressing Football.
Brendan Rodgers was appointed Liverpool manager when he was 39. Eddie Howe is 41 and, mark my words, he will 100% get a chance at a top six club in the next few years. Excellent manager. The template for all young British managers.
