Retro Silly Season

[Theunser]

I've been reading the 'Almost Moves' thread on Autosport Forum and I found some interesting things.

But still I have some questions about some possible driver transfers:

1, Barrichello had an offer in 1992 from an F1 team.
Does anyone know which was that? And also what teams he talked to about a potential debut for 1993?
(I know about Tyrrell, and obviously Jordan)

2, What was Modena's other options for 1992?

3, Did Mauricio Gugelmin ever had a chance to move to a top team, and what other offers he had in 1992 instead of Jordan?

4, Eddie Irvine was interesting for many F1 teams at the end of 1993. One was Jordan. But which were the others?
