Manchester City are not expected to make any big moves in the January transfer window after spending more than £150 million in the summer, bringing in the likes of Kevin De Bruyne, Raheem Sterling and Nicolas Otamendi.
But with the Blues still challenging for silverware in all four competitions, Manuel Pellegrini's squad will be stretched to the limit.
They have already suffered major injury setbacks to captain Vincent Kompany and midfielder Samir Nasri while Sergio Aguero, Pablo Zabaleta and Wilfried Bony have missed large chunks of the season.
Pellegrini could bolster his numbers by taking talent from sister club New York City.
The two clubs have enjoyed a fruitful partnership that saw Frank Lampard move to the Etihad last term while young stars Shay Facey and Angelino made the opposite journey to the Bronx.
Here are five players who could make an impact in Pellegrini's squad:
David Villa
The Spanish striker was named New York City's most valuable player at the end of the season after he scored 18 goals.
City have been short of striking options with first choice forwards Aguero and Bony missing large parts of the season through injury and just young Nigerian forward Kelechi Iheanacho for back-up.
Now 34, the former Barcelona star would seem a perfect fit at the Etihad. He still has the sharpness and eye for goal which could boost City as they bid for trophies on four fronts.
And Villa may be tempted by the opportunity to team up with former teammate David Silva, who he enjoyed playing with previously at Valencia and Spain.
Khiry Shelton
Shelton is an exciting prospect and has just been called up to the United States national team's training camp. The 22-year-old striker was the No. 2 overall pick in last year's MLS SuperDraft and after being slowly incorporated into the squad, he finished the season with one goal.
Shelton's football education would certainly be enhanced by a period in Europe and mixing with the stars at City. And the young striker may be capable of making a contribution, with Pellegrini's men having to balance commitments in four competitions.
Kwadwo Poku
One of the successes in New York's debut season, Poku made 27 appearances and scored six goals. He also looked more than at home playing alongside Villa, Frank Lampard and Andrea Pirlo.
The midfielder is a product of Ghana's Asante Kotoko academy, which has produced the likes of former Leeds United striker Tony Yeboah and ex-Bayern Munich defender Samuel Kuffour.
After spells with Georgia Revolution and Atlanta Silverbacks, the 23-year-old has a growing reputation. Poku was one of five New York players to train at the City Football Academy ahead of the 2016 MLS season, so Pellegrini will have been able to check out his potential at close quarters.
Frank Lampard
The England midfielder joined Manchester City at the start of the 2014-15 season and became so vital that he extended his loan for a further five months. It caused some embarrassment for the City Football Group with the English side effectively pulling rank by holding on to one of New York's marquee signings.
Lampard made his mark with influential performances and crucial goals -- not least a late equaliser against his former club Chelsea and the winner away at Leicester City.
His homegrown status also makes the 37-year-old an attractive prospect but New York fans were slow to take to Lampard after his delayed arrival and would not be happy to see him head back to England.
Andrea Pirlo
The veteran midfielder has ruled out a return to Europe this winter after vowing to see out his contract with New York City.
But Pirlo is determined to be part of Italy's squad for Euro 2016 and his case would be enhanced by a return to Europe. His quality is unquestionable, and even at 36, the Italian is still capable of dictating the game as a deep-lying midfielder.
Pirlo has no Premier League experience but as a two-time Champions League winner, his European know-how would be invaluable.
