Manchester City take on West Ham United at the Etihad Stadium as they look to improve their position in the Premier League.
Four defeats in their last six Premier League fixtures have effectively ended Manchester City's chances of retaining the title as they are currently 15 points behind leaders Chelsea.
To add insult to injury, their bitter rivals Manchester United were able to record a convincing 4-2 win over them in the last fixture, sending the Citizens' crashing down from the second to the fourth position.
Now City must concentrate on winning all their remaining fixtures as more slip-ups could see them surrender their Champions League spot to the fifth placed Liverpool, who are only four points behind the defending Champions.
And manager Manuel Pellegrini admits that his side now need to learn from their mistakes and focus on winning their remaining Premier League fixtures.
"I think the players are conscious we don't have results that we deserve," the Chilean told ESPN. "We have to be clear why we are not having the most results, which mistakes we are making."
"Two or three balls change the performance of the whole team, so it is very important to have the correct 'diagnostic' about the team, about what we must change, what we must do in the future."
City has been heavily criticised for being very predictable this season and using the same tactics in each and every game.
But the former Malaga boss insists that he knows what he is doing and the problem is not in his tactics.
"Every manager knows how we work, how we play. The problem we have this year is that we've scored 21 goals less, it's not because we are not creating chances," he added.
"If we never created chances maybe we'd change the system but we always do. We are the highest scoring team of the Premier League. The diagnostic is not that. There may be a lot of different diagnostics why it's not happened."
West Ham, meanwhile, will be hoping to take advantage of City's dip in form and do better the defending English champions, having managed to record 2-1 against them at Upton Park in October.
However, the Hammers have not also been in the best of forms of late, picking up just four points from their last six fixtures.
And West Ham manager Sam Allardyce says he is concentrating on his own side's performances rather than the Citizen's current form.
"I am more concerned about getting the best out of my team," said Allardyce, according to ESPN. "Maybe City are a wounded animal and they might come out all guns blazing or they might be tentative. We won't know until the match starts."
However, Allardyce admits that the Hammers are expecting City to put in good performance at home on Sunday.
"We are expecting them to put in a determined performance in front of their own fans."
