Fernando Alonso could be set to emerge right at the centre of the espionage saga.

Ahead of the latest hearing of the World Motor Sport Council on Thursday, it is rumoured in the Monza paddock on Thursday that the Spaniard could have been among the team employees who knew about chief designer Mike Coughlan's possession of sensitive Ferrari information.

The FIA this week reinvigorated the so-called 'spy' affair by revealing that it had received unspecified "new evidence".

German specialist magazine Auto Motor und Sport claims that Alonso and fellow Spaniard Pedro de la Rosa, who is McLaren's primary test driver, could be among the sources of the mysterious evidence.

According to the rumours, de la Rosa was earlier this year given confidential Ferrari setup information by Coughlan, who has subsequently been suspended, before passing it on to reigning double world champion Alonso.

The unconfirmed story ties in with even wilder speculation that Alonso, 26, might be deliberately delving into the spying affair so that McLaren is punished by the FIA, thereby releasing him from his unhappy tenure with the Mercedes-powered team.

Another likely source of the additional FIA 'evidence' is Nigel Stepney, who recently sent a letter to the governing body, according to the Italian newspaper La Repubblica.

In the letter, Ferrari's sacked former chief mechanic admits to meeting with Coughlan, and discussing the team's controversial floor design, "to evaluate McLaren's reaction" with "a person I respect".

Stepney wrote: "I met Coughlan in Barcelona, but I didn't give him the designs of the F2007; they were stolen from me within Ferrari."

Coughlan also recently sent a letter to the FIA, La Repubblica reports. (GMM)
