You only need to look at the banners around at their last game and listen to Leighton Baines to see that Roberto Martinez is not a popular figure at Everton.
The Toffees are winless in their last four Premier League outings and have slumped to 14th.
Martinez’ stewardship has seen the Blues score 52 league goals this season, the joint-best of anyone outside the top four, but concede 43, the joint-third-worst of any side not in the relegation zone, and it’s clear his emphasis on attack is a problem.
Therefore, the rumours that the Everton board are considering replacing the 42-year-old with Marcelo Bielsa should worry fans of the Merseysiders.
Bielsa is clearly an accomplished manager, guiding Athletic Bilbao to Europa League and Spanish Cup finals in the 2011/12 season, but he is unlikely to tighten a leaky defence.
The 60-year-old favours an attacking approach, serving as a mentor to Pep Guardiola, and his influence can be seen in Martinez.
Indeed, last season at Marseille, the Argentine’s side scored 76 times in Ligue 1, with only the dominating Paris Saint-Germain managing more, while letting in 42, the most of any team in the top five.
Replacing their current boss with someone in the same mould wouldn’t solve Everton’s problems and, if they are hoping to bring in another Spanish speaker, as the Bielsa rumour suggests, there are more conservative options out there.
The standout candidate in La Liga is Villarreal’s Marcelino Garcia Toral, who has made the Yellow Submarine very difficult to score against.
Marcelino’s side have only been breached 26 times in the league this season and that’s the best record than Barcelona and Real Madrid.
Furthermore, Villarreal have been resilient against top-class opposition, boasting two clean sheets in two meetings against Atletico Madrid, keeping Real at bay in their only encounter with them this term and drawing with Barca at home.
This defensive stability is clearly something Everton have lacked this term and combining that with the attacking talents of Romelu Lukaku, Ross Barkley and company is sure to be beneficial for the Toffees.
