The reigning Serie A champion is desperate to add a high-profile name to its attack in the summer transfer window, and the club is closely monitoring the situation of players such as Alexis Sanchez (Barcelona) and Stevan Jovetic (Fiorentina).
However, Tardelli feels that Suarez would be an even better option, although he realizes that signing the Uruguay star could be a bridge too far.
"It's obvious that a striker who scores 20 goals a season would be a good addition for any team. Good players are not cheap, though," Tardelli was quoted as saying by Tuttosport.
"Suarez would be ideal due to his power, technique and directness, but I'd say signing him could be a complicated matter. [Gonzalo] Higuain could be a more realistic option."
The 58-year-old then went on to discuss Juventus' chances in the Champions League, and feels the club could spring a surprise with a bit of luck.
"Teams like Manchester United, Barcelona, Real Madrid, Bayern Munich and Borussia Dortmund have something extra," Tardelli explained. "The Champions League is a strange competition, though. If Barcelona and Real Madrid are eliminated in this round, things are different for the other teams. And at that stage, Juventus could go far with their great organization."
Juve beat Celtic 3-0 in the first leg of their Champions League round of 16 tie, and will be looking to seal the deal at home on Wednesday.
