Tissone is looking forward to facing his former club...
The Argentine spent two years with Atalanta, the second of which was under Del Neri's tenure, but insists that he is fully focused on his duties for the Blucerchiati.
"It will be a special game," the 23-year-old admitted to Sampdorianews.net.
"But now I am only thinking about Samp. Starting well was important for everyone, and we will go into Sunday's game in the best of conditions. [Angelo] Palombo and I are similar and it's not difficult to understand each other on the pitch."
There have been many suggestions in recent weeks over Marcello Lippi picking Amauri and Thiago Motta among other players who were not born in Italy, and as a holder of an Italian passport, Tissone is also eligible for the senior Italy team.
However, the former Udinese midfielder is not convinced that he would accept a call, should it come.
"I feel 100 per cent Argentine, although the team is currently going through a difficult time. To be selected in the Italian team would be a great pleasure, but I cannot say if I would accept the call or not."
