It would be just about typical of the bad luck Arsenal have had to deal with if Alexis Sanchez was to be ruled out with another injury, just when the Chilean international had found something close to his best form once again.
Thankfully the game against Watford today was well won and the points were safely in the bag when Alexis appeared to pick up a knock, so Arsene Wenger had no hesitation in taking him off straight away. And if he did have a problem then it will probably not be a serious one because he was moving fairly well and it may just have been a precautionary measure from the boss.
The worrying aspect of it all, though, is that it looked like it was a hamstring tweak and that is the same problem that saw him miss around two months of football either side of the festive period. If the striker has got an issue with his hamstring, no matter how minor, it could well mean him missing at least one game.
Next up is a massive game for Arsenal away to West Ham and we really need as strong a side as possible out on the pitch for that or the late title challenge could be over before it has begun. Surely Arsenal are due a little bit of luck are we not?
