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 goalkepper 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 title contender 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.
