If this is his first 4 rating ever since, then I guess he is going to have a bad season. Maybe, Poot might be better. But I have never seen a good player make a 4 rating. Like I said earlier, the fault might actually be from your training regime. When players don't get enough training it results in poor rating.
If it were me, I will start looking for a new goalie especially now the season is only starting.
I had a similar problem last season, I train well but I was still loosing games I could have won or drawn, till I noticed my defence was leaking too much. But it was at the end of the season I noticed.
You had same quality with your opponent but he scored you 4 goals in first half, if not for your fierce attack that game for end 5 or 6 - 0
