Fredi came through 63 minutes of a reserve team draw against bottom placed Coventry on Tuesday - scoring a goal to boot - and says:
"It was about trying to test my groin, and it was all right - although I was a bit short physically."
Despite being out for two months plus with his problem, he says:
"I was not anxious, really, because I have been training quite hard for a few weeks now, and it has felt okay.
"At the moment I am all right; I am going to train the few days that are left and I am going to see on Monday if I play from the start or if I am substitute - I don't know yet."
Glenn Roeder spoke to Fredi after the match and he says:
"He came to the game and saw that everything was all right, and said he was happy for me, but I don't know what will happen on Monday at the moment."
Fredi's desire to get involved again mirrors that of Don - a keenness to play intensified by the wish to help the Hammers off the bottom.
"It is very frustrating; we are not doing very well and you always want to be part of the team when things are going wrong," he explains.
"I have been a bit sad for the side - and very frustrated as well - and the reason, I think, for the situation we are in is confidence.
"Because we have lost so many the team doesn't feel very good and we need to get back this confidence; if we don't win a game soon it will keep going this way.
"We just need three points from the next game to feel more confident; at the moment it is still going the wrong way - and we need something to put it right."
Comparisons with last season have been made in the light of West Ham's slow start but he candidly admits:
"It is worse than last season because from the beginning to the end we were winning nearly every game at home; this year it is different and we can't even get results at home."
All the more reason, says Fredi, to show real character, and he adds:
"We have to start positively for the next game, even if it is so hard because of the lack of confidence - we have to be positive."
Fredi is full of praise for the way Jermain Defoe has been playing in difficult circumstances with no one to share the burden that he and Paolo Di Canio have had to bear.
Glenn Roeder has stated that he would have liked to have taken the youngster out of the firing line but Fredi's injury has made it impossible, and Fredi says of Jermain:
"He is working hard - it is always difficult to work up front against a team from the Premiership.
"I would like to help him, and Paolo as well; I will do my best to do so as it is very hard and we have to stick together."
Clearly, Fredi's height has been missed, and he says:
"We have been suffering and Jermain can't receive balls in the air as he is too small for that; we have to give him the ball to his feet.
"But if we don't get possession of the ball we can't do this, so he was struggling up front, which is completely normal.
"If I play next to him I can help him in the air and hopefully I will play with him or Paolo, or all three of us."
Indeed the scenario of Fredi playing alongside Paolo and Jermain next week is not too far fetched with Eduoard Cisse suspended and Steve Lomas doubtful, and Fredi claims:
"It is completely possible because Paolo can play in a different way, as a striker/midfielder, so he can play with two strikers ahead of him without a problem.
"The manager has to see if it is really useful to use the three of us; I would certainly like to play, but if I do I don't know how long it would be for."
The home game with Arsenal on August 24th seems a long, long time ago now, and Fredi, whose saved penalty after he had earlier scored proved to be the turning point of the game as Arsenal fought back to 2-2, admits that if three points had been collected that day the current situation would be far removed from what it is.
"It would have been completely different because we would have a lot of confidence," he insists.
"We started quite well in that game, and performed well overall, but West Ham is always like this; we can do a magnificent game and then be poor the week after.
"It is always the same problem - we have to be consistent."
The hope is, with Fredi's all important physical strength allied to technical ability, he can help provide just that quality.
