Birmingham City's dismal season continued yesterday as they were beaten 1-0 at home by Luton Town.

Aitor Karanka's side went into the game having won just once in their last 11, which left them second from bottom in the Championship.

Therefore, the game against the Hatters was seen as a crucial one, but Blues didn't perform, as Dan Potts' first-half strike was enough to seal the points for the visitors.

It increased the pressure on Karanka, and fans will understandably be worried about the way this campaign is going to play out.

Here we look at THREE things we learnt from the loss...

Karanka still doesn't know his best team

The Spaniard made changes to the team once again, and it didn't pay off. Then, he'd used his five substitutes by the 70th minute.

Quite simply, Karanka still doesn't seem to know what his best team is, the best formation to use, and he doesn't even appear to have a group of players that he can rely on each week.

To be like that at this stage of the season is hugely concerning, and that is all down to the manager.

The home form is alarming

Blues have the worst home form in the league, with just nine points from 15 games, and they've only scored nine goals in that time.

That's disgraceful really, and the club are lucky that the fans aren't in the stadium to voice their anger. Again, this is on the boss, as the side need to be playing with more attacking intent on their own patch.

If they are to stay up, results at St. Andrew's need to change immediately.

Relegation is a major possibility

Most Blues fans will claim they've known this prior to yesterday's game, but the manner of the defeat to Luton felt like a side who are going down.

Whilst Nathan Jones' outfit are a decent team, this was a winnable game, yet the performance was extremely poor.

One shot on target illustrates a team low on confidence, and with sides around them picking up points and having momentum, Blues look in a very bleak situation, even if they are only a point from safety.
