Bristol City are chasing promotion to the Premier League, as they currently sit fourth in the Championship table as the Christmas period approaches.

The Robins missed out on a play-off place last season as they faltered towards the end, and Lee Johnson will be looking to change the fortunes of the Bristol club as they hunt for football in the top flight.

The club may have the infrastructure, stadium and the board to make it to the top flight, however, questions are still being asked about whether they have the ability on the pitch to reach the top flight.

Here are three reasons why Bristol City aren't ready for promotion yet...

Lack of Premier League quality players

Bristol City have a squad that is more than capable of finishing in the top half of the Championship at the very least, but they lack players who have been there and done it in the top flight as well as players who could be capable of doing it.

Out of their squad, Nathan Baker, Ashley Williams and Andreas Weimann are the only three players who achieved consistently at a high level in the top flight for a sustained period of time, while Josh Brownhill and Han-Noah Massengo have the potential to make it in the Premier League.

Still inconsistent

Despite having lost just four games in the league all season, the Robins will need to be more consistent with their performances and results if they are going to become a Premier League side.

They have drawn eight of their 21 league fixtures so far this season, and only won nine, as the Robins supporters have been growing increasingly frustrated with the inconsistent form that the players are showing while out on the pitch.

Johnson has no managerial experience in the Premier League

Despite having beaten Premier League sides such as Watford, Crystal Palace and Manchester United while he has been in charge of the Robins, manager Lee Johnson has no previous managerial or coaching experience in the Premier League.

He has managed to get the best of top flight opposition on a one-off occasion, however, he would need to prove that he has what it takes to do it week in and week out if Bristol City were to sustain themselves in the Premier League.

With the abundance of manager superstars in the Premier League right now, Johnson would be going toe-to-toe with some of the world's best tactically and while he is clearly a talented manager, he may not be ready for the Premier League just yet.
