Lee Bullen faces the first big test in his tenure as Sheffield Wednesday as his team take on Luton Town.

Ordinarily, a home match against a recently promoted team would, on paper, be a clash that the Owls would be confident of winning, but Bullen has just experienced his first defeat as Wednesday boss and he will be under pressure to respond in the right manner.

Luton will be no walkovers too and have been competitive in all their matches so far, and can consider themselves unfortunate to be winless from their three games, despite playing strong opposition in each.

The Owls received many plaudits for their performances in their opening two games and although they dominated Millwall in terms of shots and possession, they ultimately fell to a 2-1 defeat against a team which had ten men for the majority of the match.

A failure to break The Lions down means Bullen will have to go back to the drawing board and work on different things in training, an area in which he can put his specialist skills to good effect.

Bullen is a good coach, but he lacks tactical nous, and that was shown up at The Den.

The decision to bring Barry Bannan on was probably the correct one but a more experienced manager would have retained the width that Dominic Iorfa and Kasey Palmer provided, and taking them off played into Millwall's hands by making the team too narrow.

With hindsight it is easy to criticise areas where Bullen went wrong but he went with a strong starting line-up which was only altered slightly in an attempt to combat Millwall's aerial threat.

Despite that, doubt could begin to grow about Bullen's ability, and a failure to win against Luton will likely increase that further, and lead to a halt in the cascade of calls to hand him the job on a permanent basis.

If Bullen's tactical naivety is on display once again then there will be concern about his suitability and whether the job is too big for him to take on. After all, he has worked as an assistant for a number of years and done well in that role, and there is often a reason why assistants are unable to make the step up.

Having a strong connection with the squad can only get managers so far and if Sheffield Wednesday fall behind on Tuesday, then Bullen may not have the answer to turn things around.

Despite the club's lack of action in their search for a permanent manager, Bullen must surely only have a limited period to prove himself. He started well but things could quickly turn sour, so picking up a win against the Hatters is vital in maintaining his managerial ambitions.
