Pirelli is now waiting for just one signature on its agreements to remain as F1's sole tyre supplier next season, having finalised terms with all eleven teams ahead of the Italian Grand Prix.

Unfortunately, the missing approval comes from the sport's governing body, with the FIA continuing to dally on its confirmation amid rumours that it may be sounding out Michelin as an alternative.

Pirelli motorsport director Paul Hembery, who has already warned that any switch of supplier at this point in the season would be nothing short of 'farcical', confirmed that the eleventh team agreement had been put to bed in the build-up to Monza and, with promoter FOM already on board, is now just waiting for FIA president Jean Todt to complete the set.

"We have agreements from all the teams, we have agreements with the promoter," he confirmed to journalists at Monza, explaining that several notable deadlines were already looming.

"We've been working on 2014 and beyond for quite some time. In two weeks' time, we are meant to be giving the data for next season's tyres, and the wind tunnel tyres in three weeks. We've had no indication that there's any issues [with the supply contract] at all."

The teams, too, are expecting Pirelli to remain as the sport's supplier, and are designing their cars accordingly, with Red Bull's Christian Horner claiming that the uncertainty wasn't necessarily hampering the process.

"Not at all, because we don't know what to expect from Pirelli," he said, aware that the tyre specification has changed from year to year, often at the behest of the FIA, "[The situation] seems to vary from weekend to weekend. I think they're finalising their plans, but it's the same for everybody."

Ferrari's Stefano Domenicali, meanwhile, sounded a note of caution over the delay, concerned that it could affect the development process further down the line.

"One thing that I would say, in all fairness, is that it will important to give them the possibility to test when the new cars are there," he noted, "For example, in wet conditions, we need to make sure that we will be able to do it before arriving to some [race] weekend where we will find wet [weather] and suddenly discover something that was not expected. I think we need to also consider that."

Hembery has intimated that next year's tyres are likely to be more conservative than those produced in recent seasons, with the teams having enough to deal with following the decision to move to an all-new technical programme centring on the introduction of turbocharged V6 engines and greater regenerative technology.
