Manchester City are in a title battle in a packed festive period, with a January transfer window to look forward to alongside the Champions League - but it won't stop recruitment chiefs from planning for the summer ahead.
A key part of City's success over the past decade has been their transfer business. For example, Julian Alvarez and Erling Haaland, two of football's finest young strikers, were bought for a combined fee of £65million - less than the overall fee which Liverpool will have to pay Benfica should Darwin Nunez reach the add-ons in his contract.
Add Sergio Gomez at £10m and Manuel Akanji at £15m, and it is no surprise to see why City are the kings of the transfer market of those in the top six - especially when you consider the amount of money Chelsea, Manchester United and even Everton have wasted in recent years.
However, there is a chance for them to become even more financially astute in the summer, with a number of top-quality players out of contract at the end of the season. Here are four players the reigning champions should look to buy if they wish to save millions in 2023.
Ilkay Gündoğan is out of contract in the summer, meaning City could do with a player who is versatile in the No.6 and No.8 role just like Gundogan if he leaves. Tielemans would be a superb addition on a free transfer.
Just 25 years old, the Belgian has played 135 games in the Premier League, he's made over 25 appearances in the Champions League and has national team experience with 58 caps for Belgium already.
Arsenal have also been linked with his signature, and if they carry on the superb trajectory they have been on under Mikel Arteta, it would also limit a title rival from gaining a superb player for nothing.
City have already taken one of Borussia Dortmund's superb young talents over the last year in Haaland, and they've been linked with doing so again with Bellingham - why not make it three with Moukoko?
The youngster has notched 59 appearances for the Bundesliga giants since making his debut, and even played in the World Cup for Germany, becoming their youngest-ever player to feature in the most famous tournament on earth.
An incredible young talent, he could even be loaned back out to the Signal Iduna Park whilst Julian Alvarez and Haaland continue to work their magic at the Etihad Stadium.
Okay, this wouldn't exactly save City 'millions' - but it does fill a huge void.
Scott Carson, who has been at the Etihad since 2019, is one of City's homegrown players and, as seen in behind-the-scenes clips, is a popular figure in the dressing room - though his contract expires in the summer.
Bettinelli would fill the void left by the veteran shot-stopper were he to leave this summer.
With Gomez struggling to adapt to life in England, Joao Cancelo could do with some back-up on the left-hand side of defence.
Guerreiro would offer experience having enjoyed 147 Bundesliga appearances, 40 Champions League outings and 61 Portugal appearances, including a goal at this year's World Cup.
On a free transfer and with glowing recommendations from Haaland, Gomez, Gundogan and Akanji, Guerreiro would be a great signing.
