The phrase “There are three kinds of lies: lies, damned lies, and statistics” is certainly appropriate when discussing football data at a time when data is now readily available to the public should they be inclined to look at it. Manchester City have tried to raise the bar by offering data in the hope that some bright blogger/analyst will be able to add to the debate about improving performance via analysis of the data.
In this article I want to show how important the analysis of data is but at the same time I am hoping to push the boundaries in terms of stimulating interest in raw football data by looking at data from the 2008-2009 onwards including the current season to find out if there is a correlation between conceding and the strength of a team.
If we look at teams that regularly occupy the Championship League spots and the Europa League places we see a level of consistency that the other teams cannot produce. But are there any variables that preclude established sides such as Spurs from considering winning the EPL?
We can see that Arsenal and Manchester City have both conceded first 59 times in the sample and Man City have been the team that have consolidated their position as a Top 2 team while Arsenal have declined in status but have maintained their levels in terms of being consistent regarding the the number of games a season where they concede first. We can also see that although Manchester City have drawn a higher % when conceding first (27%) , it is Arsenal who have only lost 49% of games when conceding first, which is much better than Manchester City as they have lost 57% of the games.
Manchester United have conceded the first goal of the game, the least amount of times (45) and Everton the most (76). There are some key issues to discuss.
I could discuss that the Manchester United midfield is not good enough to protect the defence or that this is a random event that I cannot explain but I will leave that to other football bloggers because as long as Manchester United win their games when they concede first, the relevance of this new trend is weakened. It means that in the EPL when Manchester United concede then there is still expectation that they will win but this is dependent on so many factors so we cannot just put a value on Man United beating Fulham when Fulham scored on 3 minutes to lead 1-0.
- What is the expectation of further goals given that Fulham have scored the first goal on 3 minutes and are the away team?
- Will the expectation of goals increase (greater then calculated before the game started) or impede for both the teams or will the early away goal have an effect on just one team?
What value do we put on Carrick having to play as the emergency centre-half in that game or the laughable own goal by Vidic in the game or the fact that Rooney started on the bench due to lack of form and Nani did not even make the bench for the game?
It is easy to put a figure on the expectation of Man United winning at 1-0 down but much harder to justify that figure without the inclusion of several other variables such as the pitch conditions, the strength of the shots, the accuracy prevention of both teams, the weather conditions, the motivation of both teams and the possible under performance of players on the day plus the fact that Carrick had to play in a position that I do not think he is best suited to. But when Carrick has played centre-back what % of games have Manchester United lost compared to the average which also is irrelevant unless you look at the strength of the team that they play each time Carrick has played in the role.
I remember reading in the paper on the last game of the season(2010-2011) to be advised that Manchester United do not score many goals during the last game of the season. The final score was Manchester United 4 Wolves 2 . The flaw of the argument is that the strength and motivation of both teams and the time of the first goal and the goal expectation and any rain or beach balls or referee blunders or freak goals or Red cards could alter the course of the game.
As Man United are winning 72% of their games when conceding first this season then I do not believe Sir Alex will be losing too much sleep. A problem may occur if they are losing 1-0 to a team like Dortmund or Bayern Munich as they will find it rather tougher to get back in the game than they did against teams at the level of Fulham.
Sir Alex Ferguson has acknowledged that the biggest mistake he made was letting Stam go who I would consider to be one of the best defenders in the History of Manchester United.
Do we believe the story that Sir Alex was advised that Stam was tackling less in games and as a result a perceived view that his best days were behind him or was it as Stam has publicly said that Man United were in financial difficulty and needed the cash flow urgently.
At the petrol station he parked his car and got in with me. He told me that I had to be transferred. Then he said: “Will you please move to Lazio quickly?”
If we look at Everton they have consolidated their position as a top 6 side as far as I am concerned, but recently I was listening to the radio to be advised that “Everton have over achieved this season” and that this is a blip and their levels of performance will drop.
They did not offer any data to back up their prediction and I offer the following in the case for the defence of Everton
Everton have conceded the first goal in 76 games during the sample but the levels remain very consistent and it has not impeded them from a high finish as they have only lost this season 9% of games when conceding first and in the sample overall they have drawn 34.66% and avoided losing 53.94% of the time. Only Manchester United in the sample of games can boast a better % which is 60.

My first taste of football in a stadium was Gillingham V Aston Villa 1971 and I still have the programme which cost 5p. I have been lucky to have seen a number of Cup Finals but missed the Sunderland goal in 1973 as I was in the toliet. I have recently been watching Margate and also watch around 50 other matches a month on my computer .
