Former Inter Milan striker Aldo Serena believes the Nerazzurri need to sign a top centre-half this summer.
Inter are well on track to clinch the Scudetto this season and Serena insists they should be preparing to build on what they're achieving this term.
Serena told La Repubblica: "Inter Milan: the Scudetto is done.
"They need to start from (Cristian) Chivu's ideas, understand which module he wants to start from, and act accordingly, even at the cost of making painful choices.
"It wouldn't surprise me if it changed anything. I'd start with a big central defender: (Gleison) Bremer would be a great name, but Kim (Min-jae) is a good name too.
"And a goalkeeper. (Giglielmo) Vicario would be fine."
Serena added: "I had no doubts about this attack, Bonny included. However, I would like a player at (Desire) Doué, Kvara (Khvicha Kvaratskhelia), (Ademola) Lookman or Nico Paz. It's not easy to take them, but the characteristics must be those."
