In typical Roberto Martinez fashion, the Latics put up a good show for the first 35 minutes and were hit by a sucker punch ten minutes before the break.
Florent Malouda scoring the Chelsea goal that took the wind out of the Latics' sails.
Half time came and went and Martinez had visibly fired his team up to take back Chelsea's 1-0 lead. However with the skill of a team that won the league last year, Ancelotti's men picked the Latics off and scored two breakaway goals early in the second half to kill the game off.
It was then disappointing to see the Latics conceed three goals in the final ten minutes as the collapse of old came back to haunt the DW Stadium.
What is more frustrating is to look at the league table and see the Latics record the worst ever start to a Premier league season .
A 6-0 defeat to Chelsea, in the form that they are in, is not all that bad as an isolated incident. But aligned with a 4-0 home defeat to Blackpool, it is not acceptable.
The pressure is now on Martinez because he was more focussed on beating Chelsea, and putting on a good show for the cameras, than he was winning the bread and butter games, such as Blackpool at home, that will keep the team in the division.
Had his side performed the first 35 minutes against Blackpool as they did Chelsea, we would have beaten the Seasiders.
The signs of improvement were there and had we been playing a lesser team, the Latics would more than likely have won the game. However Chelsea are brimming with confidence and it showed.
Should he get the sack, Martinez has only himself to blame after the debacle against Blackpool last week, a performance that was unforgivable from a team of highly paid so called professionals.
Here is the reaction of the two managers.
Roberto Martinez
I am shell-shocked at the score-line, because I just couldn't see that coming at all after the performance in the first half. We need to correct certain aspects, but it is disgraceful to have to be explaining away a 6-0 defeat from that game.
The players gave everything, but physically and we could not maintain our first-half performance. We were in the game until the third goal went in, but the goals that followed were far too cheap.
It was a heavy defeat, but we can take many, many positives from the first half and that is what we must build on.They scored from their first shot on target, then with their first effort in the second half, and mentally it is tough for you to respond.
Goals change games, individually and collectively, and today we have learned a few nasty lessons. When you are playing against outstanding individuals, they are going to make the right decisions and hurt you.
But to concede goals in the manner we did is going to be damaging, and we couldn't get back into the game. We cannot be that weak and naive when things are not going our way, and that has been the case for the past year not just this season.
It's something we need to eradicate from our football club quickly. I couldn't have been any happier with our first-half performance.
We were the better side in every single department and we didn't deserve to be 1-0 down at half-time. In the second half we did have some half-chances but we just didn't have the quality to make the most of them.
It's time to stop giving silly goals away and do justice to the quality we have got. I can understand the fans booing us off because it is another game that we have not got any points from.
I would just ask the fans to forget about the score-line, if they can, and get behind this group of players.
Carlo Ancelotti
I think we are trying to play the same football that we played last year. We started very well this season and scored a lot of goals, showing good football.
We have to know that today was a tough game and in the first half. Wigan played good football and put strong pressure on the pitch, maybe they spent a lot of energy in the first half.
The second half was easier for us to have more opportunities to score. In the first half we had a lot of difficulty on the pitch and were not able to play our football because there was not the space.
I think at that time we defended very well, we didn't give Wigan the opportunity to score and we waited for the right time to score.
This is important because in football you have to be able to defend and attack. It is impossible to have total control of the game with possession, sometimes you have to defend and in the first half we defended very well.
We have a lot of skills, now the best quality is we are able to do a fantastic counter-attack, we have strikers who are fast with ability, so when we have space it is difficult to control for the opponent.
Obviously we wanted to win the game and to play well, and we did both. We won two games, played good football and scored a lot of goals but we are focused to play good football.
It is impossible to think we are always to score six goals in a game, this is not real football, this is Playstation. It never happened to me, but we have to stay in focus for the next game, try to win the next game and show good football.
Next game
To compund matters it is the easy trip to White Hart Lane for the Latics next week, the scene of the 9-1 defeat last season. A repeat is surely not possible?
Just the matter of Hartlepool in the Carling Cup midweek to get some respite.
