As i think it's pretty much obvious now, the team was suffering from a mental block. Segunda is very tight, it's not that we have the worst players among the 22 teams (obviously though with the 6th higher budget in the division we should have got better players). Anyone can win anyone.
What FV managed to do (and this is why we got him) is to bring back the faith to the players and fans. He did that. The team now has the proper intensity (what we saw in the second half yesterday).
Now the challenge is to keep that intensity. While yesterday's game was a "win at all costs" game, now there is the fear of relaxing.
We are just 1 point from safety, the players could fall in the trap "oh, it is actually easier than what we thought" and feel that job is almost done.
If we keep that intensity we will be saved.
