Kolo Toure is confident Liverpool will make up lost ground on their rivals to land a top four spot and Champions League qualification for next season.
The Reds missed the chance to close the gap on the Premier League's top four as they were held to a goalless draw by a determined Sunderland side at Anfield on Saturday.
With manager Brendan Rodgers having instilled a slightly more defensive approach in recent weeks -- which has had the desired effect as they are now unbeaten in four matches in all competitions having lost their previous four -- it has made it tougher to break down sides, particularly at home.
Having edged past Stoke last week they could not manage a similar feat against the Black Cats, but although he watched another opportunity to stake their claim for a Champions League spot slip by, Toure is optimistic things will continue to improve.
"We knew it was going to be a tough game. They defend very well, they showed that against Chelsea [0-0 draw last weekend]," said the Ivory Coast defender, who will now concentrate on Tuesday's must-win Champions League match at home to Basel.
"At the end we have one point, which is hard to take but this league is tough and every team fights -- Newcastle won against Chelsea which shows this league is really difficult.
"It is better but last season we did much better than that. We have had a difficult start but we are catching up slowly and surely. There is more work to do, definitely.
"Last season we were outstanding in every area and going forward it was amazing. Defensively we were strong, but this season has been difficult.
"When you have a tough start it is always difficult because the confidence is not always there. We are catching up and the team feels more secure and we need to keep going in that direction."
