"The biggest thing in football is putting the ball in the back of the net.
"It requires talent, quality and organisation as a team. To have different goalscorers gives you a stronger threat that makes you harder for the opposition to stop. You can never have enough scorers.
"More than anything though, it has been satisfying to see the right balance we have had in being a strong team defensively that has accumulated very good landmarks.
"Having three clean sheets in the opening three [away] league games hasn't been done before and it shows you how hard that is. That hasn't been at the cost of having the normal attacking threat or focus that we bring in our performances.
"The amount of chances we have created has allowed different names to get onto the scoresheet, but as a whole, we have a really balanced team in every performance and that's a very nice platform to build our season on."
While Romelu Lukaku has not been on the scoresheet yet this month, Martinez feels the goals will come if he continues to create the number of chances he has been.
"Rom has started the season really well, as has Ross and all the players that were involved in the World Cup two summers ago. They had a really good break this time, were able to work with the team for a full pre-season and that allows a footballer to be ready.
"Rom, as with any striker, goes through good moments in front of goal and tough moments, but that doesn't change the enormous role he has in our team and how important he is for us.
"I'm very pleased with where he is and the next group of fixtures that he could have an impact on. We were disappointed we couldn't score at Swansea but you look at the amount of chances he created and as a player that's important - if he creates that number of chances he'll have an incredible return in terms of goals."
The manager also commented on the status of defenders John Stones and Seamus Coleman, refusing to rule the pair out of contention for the Monday tie.
"We have been pleased with John's reaction to treatment in the last two days.
"I still think the next 48 hours are going to be important and I wouldn't say that he isn't going to be in the squad - it's too early to make a decision. It will be touch-and-go for the West Brom.
"Seamus is already working on the grass so he could well be involved in the game on Monday.
"Both he and John have been progressing well, as have everyone else who has been receiving treatment.
"The squad should be the same that we had against Reading and Swansea, with the possibility of having John and Seamus in that squad."
Martinez also spoke about the side's form in the first three away games, where they are yet to concede a goal.
"Our focus needs to be exactly the same as it has been in our away performances - we have kept three clean sheets in our last three away Premier League games and that is very difficult to achieve.
"We have to be able to be ourselves, which is scoring goals and breaking down what is one of the best defensive units in the Premier League."
West Brom have been in a decent nick of form themselves, and Roberto knows the Blues need to be at their best.
"I think West Brom are in the best moment of their season so far. It's been really clear that since the window shut there has been a real focus and their best performance arrived against Aston Villa in their last game. I thought they were very impressive.
"They have always been a team that is hard to break down and that defensive organisation is very clear - the clean sheet against Southampton highlighted that.
"We know what to expect - a very experienced side who take pride in themselves in playing at home in front of their fans, and a team that is able to score a goal."
Midfielder James McCarthy, who has some indifferent games this season, also spoke, saying he felt encouraged by the Blues start.
"We are not getting carried away. We had a tough start in terms of the games and we've got another tough few games coming up, so all we're focused on is each game as it comes.
"Of course we want to build on the start we've had and we believe we can.
"We want to achieve things at the Club, get into European places, that's the aim. But we won't look too far ahead because it is only the start of the season.
"Come January we can look again at the table and take stock then. There will still be a long way to go in the league but we can weigh up from there where we want to be going."
McCarthy also commented on the challenge facing the club at The Hawthorns on the Monday night game -
"He [Saido Berahino] is obviously a good player and was linked with a few clubs this summer. But it's not just one player we need to watch because we know West Brom are a dangerous team. They will come at us on Monday night.
"Their manager has a proven track record of doing well in the Premier League. But we will have a game-plan and we'll work on it this weekend.
"We will try to get maximum points, as we have done with our other away games."
