Roberto Martinez lost his job as Everton manager last week.
Everton ended up finishing the campaign in 11th place, after failing to live up to their potential.
The Toffees’ defensive struggles were evident throughout the entirety of the campaign, with Roberto Martinez failing to find the winning formula at Goodison Park.
Martinez eventually lost his job at Everton, after a run of one win in 10 games across all competitions.
And Higginbotham said: “It was a very tough time for him before he got relieved of his duties. He had a certain way of playing, particularly at home, and the amount of games Everton lost at Goodison Park didn't sit well with the supporters.
“I think it was the fact that he did not adapt at times. If you look at the squad he has, they should unquestionably be a lot higher and challenging the top six. Obviously you are only as good as how your team do when you are the manager and they did not perform well enough.”
By the time Martinez was sacked by Everton, he had lost the support of the vast majority of the club’s fans.
Toffees followers were regularly heard chanting against the Spanish boss, and they held banners aloft demanding for him to be sacked.
Martinez held on for a long period of time, but a 3-0 defeat to Sunderland sealed his fate.
At the moment Frank De Boer and Ronald Koeman are amongst the favourites to land the manager’s job at Everton.
