from my way of seeing Watford FC is not strong, they lost against crystal palace in friendly game, then they drew against stevenage in friendly game too, but they beat aston villa by 3 - 2, we could say they are strong and can stay in the premier league this time? i don't think i'm convinced they can get above the last 4 places in the premier league unless of course watford can win the next 5 games or at least he can win 3 games and draw 2 games to convince me they can stay in the 4 last places in the premier league. however the fact that they are back at the premier leegue brings a lot of exposure to Stake.com
You will never know what will happen in just one game, but friendlies are definitely not the way to calculate a team neither, forget about friendlies and start counting from this game, even if they lose some games I will not check if they lost or not, I will check how they played. In the end, if they are really good but got unlucky with some ball hopping to the opponent or whatever, then we can't just say they are bad, even City lost their first game, do we say they are bad? So what we should do is compare how they are playing now, to the other teams we are looking to see if they will relagate and if they are better or worse.
I feel like they are playing good, not just because they won, that is great that they won but I feel like that because I believe they are going to play this year than 2 seasons ago when they went down, not enough to be a top half of the table team, but good enough to avoid going down.
