Instead, Tallo played in pre-season friendlies for the first team. In November 2010 La Gazzetta dello Sport reported Internazionale had agreed a deal with Tallo. Chievo signed Said Ahmed Said from Inter on 31 August 2010 already as potential replacment for the reserve.

Internazionale
On 13 January 2011 Tallo was exchanged with Jacub Vojtus of F.C. Internazionale Milano. As Inter already had Simone Dell'Agnello (centre forward), Denis Alibec (forward), Mame Baba Thiam (forward) and Andrea Lussardi (wing forward) in the reserve, Tallo did not had much chance as bomber. However, Tallo still scored 2 goals in 6 league appearances. Tallo did not play any game for Inter in the playoffs.

After Roma reserve finished the group stage of the league and had a break until 2 June as the reserve had a bye to quarter-finals, Tallo finally made his first team debut. On 25 April 2012 Tallo played against ACF Fiorentina, substituting Gabriel Heinze. At that time Roma was 1–1 draw with La Viola and Enrique want more goals. However Roma lost the match by the late goal of Andrea Lazzari. Roma was doomed from the sixth to seventh, 2 points short with Internazionale and Udinese (fifth and sixth at that time) which all three teams were competing for the European berth.

In the next match Tallo replaced Bojan in the second half, at that time losing 1–2 to Napoli, another competitor for the berth. Before the match Roma had lost Erik Lamela (second of the three matches ban) Osvaldo (first of the 2 matches ban) due to suspension and force to use out-favoured Bojan. Tallo assisted Fábio Simplício for the equalizer goal. Eventually Roma got 1 key point to keep the team chasing Lazio, Napoli, Inter and Udinese as the seventh with 4 points behind.
