Carlo Ancelotti could be faced with a number of interesting decisions as he prepares his side to face Chelsea on Monday.

Everton are heading to Stamford Bridge on the back of three victories in a row and three clean sheets secured, with the latest coming away to West Brom on Thursday evening.

Gylfi Sigurdsson played a fantastic cross into the box after coming off the bench in the second half for Richarlison to head home the winner and briefly send the Blues fourth, before Chelsea's win over Liverpool lifted them to that position.

While Ancelotti's side did secure a win at The Hawthorns, their performance was far from convincing in some areas - and changes could well be on the horizon for a tough trip to west London.

We've had a look at some of the alterations Everton could be tempted to make to their starting 11 when they face Chelsea at Stamford Bridge.

Who could keep their place

This could well depend on the formation Ancelotti selects in many areas of the pitch.

However, depending on the potential fitness of one player in particular, you would expect the back four and the goalkeeper to each keep their place in the side for this one.

The defensive line have all played in each of Everton's last three matches and kept clean sheets in them all, so they will likely be given the opportunity to achieve that again.

Regardless of system, Richarlison and Dominic Calvert-Lewin will also be in the starting line-up for the visit to Stamford Bridge, fitness-permitting of course.

Meanwhile, Abdoulaye Doucoure seems to demand a regular starting place in the side these days thanks to his brilliant performances throughout the term, so it shouldn't be a surprise to see that again this time around.

Who could drop out

Again this could depend on the formation that Everton use, or on the potential return of some players to the line-up after injury or being rested for the trip to West Brom.

Both Alex Iwobi and Bernard were given opportunities on the flanks in the 1-0 win for the Blues on Thursday, but neither could make a significant impact on the outcome of the game.

With the potential for Everton to switch to a diamond or back to a 4-3-3 for the trip to Chelsea, there's a possibility neither will keep their place in the 11.

Meanwhile, Andre Gomes struggled somewhat in the first half at The Hawthorns and, despite improving in the second half of the game, other returns in midfield could keep him out of the side on this occasion.

Who could come in

Firstly, you have to look to the two men who came off the bench against West Brom.

Both Allan and Gylfi Sigurdsson helped change the game for the Blues as they secured a 1-0 win in the second half, and both could well regain their places in the side.

Elsewhere, potential returns from injury could see changes made to the Everton setup.

Tom Davies, Seamus Coleman and James Rodriguez all started in the win over Liverpool at Anfield but haven't been seen since thanks to minor injury problems.

Should any, or all, of them be deemed fit enough for the trip to Stamford Bridge, it wouldn't be a surprise to see Ancelotti turn to them and change his system once again.
