LONDON (AP) ― After seeing its Premier League lead wiped out by archrival Manchester United, Manchester City’s title credentials face a severe test when it plays revitalized Sunderland and then Liverpool in a three-day span to kick off a hectic month for the big-spending northern club.

City still tops the standings as it goes in search of a first English title since 1968, but has squandered a five-point advantage in the space of a month to lead the reigning champions only on goal difference.

The pressure will be ramped up on Roberto Mancini’s men in January, when they also play United in the third round of the FA Cup and Liverpool over two legs in the semifinals of the League Cup.

“There is all sorts of pressure and we’re feeling it,” City goalkeeper Joe Hart said.

With United hosting bottom team Blackburn on Saturday and bidding for a sixth straight league win, City is likely to go into the new year second in the table―an unusual position for Mancini’s team this season.

City has still only lost once in the league ― at Chelsea on Dec. 12 ― but the fixtures come thick and fast next month as the club aims for silverware in numerous competitions to reward the continued heavy spending by its billionaire Abu Dhabi owners.

Sunday’s trip to Sunderland has a tougher look to it after Martin O’Neill inspired the hosts to seven points from a possible 12 since taking over as manager on Dec. 3. City then hosts sixth-place Liverpool two days later, the first of three matches against Kenny Dalglish’s team in January.

“To play twice in 48 hours will make a difference at this moment but we have good concentration and in January that is important,” Mancini said.

“I’m confident we can do a good job by the end. ... United have a strong team but we are strong enough to do this.”

United manager Alex Ferguson hopes to celebrate his 70th birthday in style with a win over Blackburn on New Year’s Eve, although the visitors showed they have the stomach for a relegation fight by battling to a 1-1 draw at Liverpool on Monday.

However, stopping United at Old Trafford ― where it has won seven of its nine league matches this season ― is a different matter, especially with the home side having scored 16 goals in four straight wins since its shock exit from the Champions League.

“We reached the (Champions League) final last year and it hurts to go out so early,” United winger Antonio Valencia said. “But we are using that hurt.

“The group now tries even harder in training and we are going into games with a determined attitude because we’ve got to win something, whether it is the Premier League, Europa League or FA Cup.”

United’s impressive recent run comes despite its squad being crippled by a series of injuries that has robbed the team of all four of its center halves and three of its first-choice central midfielders.
