The possible sites of hot CNO processing for the gas which allowed the formation of ``second generation'', chemically anomalous, stars in Globular Clusters are either the envelopes of massive rotating stars or the envelopes of massive asymptotic giant branch (AGB) stars. As the massive stars destroy Lithium, while the massive AGBs can also produce it, the Lithium abundance of unevolved stars of GCs could be a powerful discriminant between the two scenarios. We show the status of art of the computation of Lithium production in massive AGBs for different population II metallicities, provide explanations for the trends with metallicity and mass loss rate of the models, and compare the results with observations. Unfortunately, today's determinations of Lithium abundance in GC stars are not sufficient, and not enough precise, to allow a choice between self-enrichment by AGB or massive star models.
