Manchester United have one of the strongest squads in the Premier League this season.
Manager Jose Mourinho has world class players to pick in every position from the backline all the way through to the front.
Even with injuries to the likes of Paul Pogba, Zlatan Ibrahimovic and Marcos Rojo, the club are still challenging at the top of the league.
They're currently second behind leaders and rivals Manchester City and look to be Guardiola's closest challengers, despite losing to Chelsea last weekend.
United wouldn't be capable of fighting for the league, or the Champions League, without a very strong squad.
The depth they have is necessary, especially now that the top English teams are heading towards a hectic Christmas schedule that will be very testing over the next few months.
The Red Devils may have a strong squad for this season, but once it finishes there are seven first-team players who have contracts that expire in June 2018.
Juan Mata, Ander Herrera, Daley Blind, Marouane Fellaini, Ashley Young, Michael Carrick and Ibrahimovic will all be made free agents in less than a year as it stands.
Arguably, none of those players are key to Mourinho's starting 11 at the moment, but with such a long season, squad and rotation players, like those, are always needed.
Out of the seven with expiring contracts, United reportedly only want to sign up four of them for another year.
According to the Telegraph, the four that are going to be offered 12-month extensions are Herrera, Mata, Blind and Young.
The reason they will only be given a short extension is so Mourinho is allowed more time to decide their futures.
The Portuguese boss is not looking to offer Fellaini a short contract because he's apparently hopeful of convincing the Belgian to stay longer.
The midfielder has become a more important figure at Old Trafford under Mourinho after spending a number of years failing to impress most United fans.
The futures of Carrick and Ibrahimovic are less certain, especially due to age and injury concerns.
Although Mourinho would probably like to keep the pair for depth, they're both arguably way past their best at the age of 36 and wouldn't get many chances in the first team next season.
