Leeds United are enjoying a superb start to the new season and that should not be forgotten. However, there is arguably one thing preventing them from running away with the Championship based on early performances and that is their manager's team selections in certain big games.

Thomas Christiansen has quickly made his mark at Elland Road and there are numerous reasons to be positive, but against the Millwall and Cardiff City, the Leeds boss got it wrong in terms of his starting XI.

Of course, that is easy to say in hindsight, and no fan questions his team's line-up if they smash the opposition. But Millwall's physicality should have been effectively countered with the inclusion of the likes of Gaetano Berardi and Stuart Dallas from the outset.

While against Cardiff, in what was Leeds' biggest match of the season to date, they left their two most impressive attacking players - Samu Saiz and Pierre-Michel Lasogga - on the bench.

Eunan O'Kane's enforced absence should not be underestimated, but it was always going to take Christiansen some time to get used to Championship football and identify each particular opponent's strengths and weaknesses.

He has got far more right than wrong, but if someone had been in his ear telling him what to expect from both the Lions and the Bluebirds, Leeds could be out in front even at this early stage of the campaign.
