What's that 'There are lies, damn lies, and there are statistics' quote? Whenever I see these xg and other stats there's a bit of me that just doesn't buy into them. I am suspicious of how they are compiled, who compiles them, and the values made up to make the stats. The only real 'statistic' that matters at the end of the day is a League Table.
Anyhow in regards of Langstaff, to me he has serious Andy Morrell vibes about him. I think he will work hard, and will undoubtedly contribute goals to a point, although obviously not to the degree he has been in League 2 and the National League, and I suspect he will be in and out of the team if he signs. My father supports Notts so I have a bit of an interest in them through him and I watched their play off games last season, so have seen Langstaff play. Granted it was only 2 games, but I suspect that is 2 games more than many of our fans have seen him. Anyhow, while his goals record is hugely impressive I wasn't overly taken by his general play, and I don't think he would suit us (as a starter anyhow). Al Hamadi looks to be a much better fit to me.
That said if MR thinks he is worth bringing in, then I will bow to his greater knowledge and get right behind him. I know I can be as wrong as the next man on such matters!
