Four years later, and this week, we saw the curtain fall on Everton’s career at Niasse, the Goodison Park club having confirmed that he would not be offered a new deal.
Martinez spent £ 13.5 million on the 25-year-old, who was brought in to replace Steven Naismith, who had been sold to Norwich earlier in the same window.
A few months later, Everton sacked Martinez after three years at the helm, following a series of dismal results.
The club praised the Spaniard for “greater integrity and dignity”, describing him as a “great ambassador” who played a “key role” in the development of young players in a statement confirming his departure.
Many things went wrong for Martinez in his last year at the helm of the Blues, but Niasse, who had no impact, let alone a “huge”, was a huge black mark against the Belgian boss.
When David Moyes left Everton a few years earlier, his starting gift was a young gem named John Stones.
The Barnsley-born boy would become one of the best defenders of Everton in his Premier League history and eventually left the club for Manchester City for a transfer fee of nearly £ 50 million.
There’s been a lot of talk about Moyes’ departure, but there’s no denying that he left the perfect starting gift when he hired Stones in his last transfer window in charge of the club.
Martinez, meanwhile, obtained the services of two other players in his last window in charge.
Shani Tarashaj joined a four and a half year contract, although he was immediately loaned to Grasshoppers for the remainder of the campaign.
“We are delighted to have found a young player who believes that our club is the ideal step to improve their quality and advance their career,” said Martinez on Tarashaj upon arrival.
“He fits very well with our style and the way we want to play the game. He is a family boy, hungry and he is desperate to fight for his place in our young talented team. “
And a youngster named Matty Foulds also joined Bury, at a cost of around £ 300,000.
Although he’s a regular on David Unsworth’s under-23 team, Foulds, who won the Premier League 2 and Premier League Cup double in 2018/19, has not made a single appearance for the Blues senior team.
And earlier this week, Foulds, with Morgan Feeney, Alex Denny, Manasse Mampala and Korede Adedoyin, left the Blues after the conclusion of their agreements.
Tarashaj remains under contract with Everton after the club updated its registration in July 2019.
His contract at Goodison Park was set to expire at the end of June, but the club has restructured its deal to split wages over the next two years and help secure the transfer of its loan to Emmen.

However, his long-term future is certainly far from Goodison Park, with him still for the first team of the Blues.
With hindsight, the writing may already have been on the wall of what was to come for Roberto Martinez.
Niasse, Tarashaj, Foulds were all players brought for the future, not at the moment, but unfortunately for the trio, Martinez could not see what was happening before his eyes.
And this is the reason why, in mid-May of the same year, the Spaniard had left, and why Niasse, Tarashaj, Foulds will all remember their stay at Everton with a huge idea of what would happen if .
