In week 15, Luton will face Arsenal tonight, and in my opinion this will be an easy match for Arsenal to get 3 points even though they will play at Luton's home ground and will continue their victory.
However, after the match against Luton Arsenal have quite a tough schedule towards the end of the year. And they will face Aston Villa and Liverpool, two of the top four teams, as well as Brighton and West Ham United throughout December.
Luton are just above the relegation zone. Arsenal is at the top. It is not difficult to predict the outcome of the match. I predict that Arsenal will win and I can bet on it. It could be a difficult game for Luton. If Arsenal do not receive a red card in the early minutes and there are no big surprises, Arsenal will be at the top again.
