Even if what you said is true, is it right to blame the condition of the pitch when the away team only lost narrowly when playing there? Especially if every pitch does have standards to be used in competitions like Serie A, so losing narrowly like that is just a very common thing and I don't think the away team should blame the facilities there. Actually Udinese weren't too bad when playing at Genoa's home ground, it's just that Udinese were unlucky enough to be able to equalize because the goal in the last minute was disallowed due to offside.
That was not one of the factors that made Udinese lose to Genoa because Genoa's performance was much better than Udinese. The standard of the field is a measure and it is a facility that must be met by the club and there are regulations that govern the issue of fields that are suitable for use or not. Udinese did not play badly, but the final finishing made them always fail to score goals.
The small defeat they got in the match made Udinese stuck in 10th place and in the future in the remaining matches they will face several stronger teams where they have to face Milan, Bologna and Juventus.
