Chelsea may have had an eight point lead whittled away by challengers Manchester City earlier in the season, but it won't be happening again says Branislav Ivanovic.
The fullback says Chelsea are a young team, but they are learning from their mistakes, and they won't be giving up their five point and one game advantage quite so easily this time.
The Blues edged another game closer to their first Premier League title in five years on Wednesday night, with a hard-fought 1-0 win at West Ham.
Ivanovic said: “We are growing as a team, and we learn from our mistakes. That's how we know that every game in every situation is very important.
“I think after the great final in the (League) Cup, this was very very important. I think the same importance, even more than the other ones because it is after the final and we don't have a game at the weekend.
“It was massive, huge, and we are so happy about these three points.
“We knew what we had to do. We knew it was another final for us, after Man City lost a game, because it gives us an opportunity not to let them close the gap again.
“I think we are one step closer, but still it is a long way to go.”
Chelsea now have the weekend off, thanks to their premature exit from the FA Cup, before welcoming Paris Saint-Germain for the second leg of their Champions League second round tie on Wednesday.
He said: “We had a great result in Paris (1-1), but we still have to think about the Champions League, because we want to go through.”
