Everton will be looking to make it three Premier League wins in a row when they travel to The Hawthorns to take on relegation fighters West Bromwich Albion.
Following wins against Liverpool and Southampton, and clean sheets in both, a win over the Baggies could see the Toffees move into a Champions League place.
Despite the hosts’ league position, Albion are without defeat in their last three games, and like Everton, they have kept clean sheets in their last two.
The visitors will be aiming to complete the double over West Brom having won the reverse fixture in September.
Dominic Calvert-Lewin's hat-trick inspired Everton to a 5-2 victory over 10-men Albion at Goodison Park.
Rodriguez and Davies doubts
Everton were without James Rodriguez and Tom Davies last time out, but when speaking to the media, Ancelotti was reluctant to reveal any details regarding their absences.
He said: “We have training this afternoon and I can’t give the precise information on this. We will check on the players in training to see if they are available or not.”
Ancelotti did reveal Everton ‘for sure’ are without Yerry Mina (calf), Fabian Delph (hamstring) and Jean-Philippe Gbamin (knee) for the fixture in the West Midlands.
West Brom danger
Managed by former Everton manager Sam Allardyce, West Brom arrive into this battle high in confidence having not lost in three games- one win and two draws.
The Everton boss says it is no coincidence Albion have kept clean sheets in their last two fixtures, and warns Everton of the difficult task ahead.
“Tomorrow is very important as it will be a difficult game against a team fighting for relegation, we will have to be motivated and focused,” said Ancelotti.
“They improved their squad in January and are playing how Allardyce wants. They are strong defensively, strong in contact and it is no coincidence they haven’t conceded in their last two games- finding opportunities tomorrow won’t be easy."
Everton were welcomed by the return of Allan to the starting line-up in Monday’s 1-0 win over Southampton.
The midfielder started his first game in two months having been side-lined with a hamstring injury sustained in Everton’s away win at Leicester City in December.
Ancelotti hailed Everton's medical staff who he says worked hard to ensure the Brazilian returned in good condition.
He said: "The medical staff worked hard to make sure he was fit and in good condition. Allan was motivated, he wanted to play and his performance was really good.”
“After two months out we have to take care so will check today if he has recovered properly and if he can play tomorrow,” the manager added.
Champions League ambitions
With Chelsea dropping points against Manchester United, the three points gained against the Saints moved Everton to within a point of a European place with a game in hand.
Victory away to West Brom could see the Toffees climb above West Ham and into the top four- dependent on other favourable results.
“Every player at the minute is involved, focused and has the ambition to play at the top- the Champions League is the top,” said the three time Champions League winning manager.
“It would be a step forward in all of their careers and they understand how important this season can be, not only for the future of the club but for the future of every one of us.”
Despite the Toffees never qualifying for the group stages of the competition, Ancelotti admits having ambition is important, and that a club as historic as Everton should be in Europe.
He said: “It is important to have ambition and for a club with such fantastic history it is normal to want to be in Europe.
“The European places will only be decided on the final game, so we have to make sure we are still there when that stage comes.”
