Mateo Kovacic hasn't always been on top form this season, but the Inter midfielder's potential is beyond debate and he is seen as a crucial cog for the future.
The 20-year-old has won plaudits for his vision as a playmaker capable of inspiring his side going forward and featured in this season's guide to the best young players in Europe in La Gazzetta dello Sport.
Kovacic showed what he can do when he provided three assists in Inter's 4-1 win over Lazio last week - an achievement that hadn't been matched in Serie A this year.
But the Croatian star hasn't always impressed this season and met with criticism from coach Walter Mazzarri earlier in the campaign for a poor showing against Juventus where he was outplayed by Andrea Pirlo.
Inter owner Erik Thohir has pledged to create a youthful Inter side and is believed to see Kovacic as central to this new generation.
According to La Gazzetta dello Sport, Thohir is determined to keep Kovacic and build a team around him, but he will need to fend off the attentions of German side Borussia Dortmund plus English giants Liverpool, Manchester United and Arsenal.
Brendan Rodgers is apparently a big fan of Kovacic and would like to add him to his ranks this summer, so Inter will need to be strong to resist a potential big-money approach.
Inter are trying to add a star striker and could need more funds to launch a bid, but the sale of Kovacic has been ruled out, according to the Italian press.
