Arsenal, Everton, AC Milan and Juventus have all been reportedly tracking the Czech Republic international, but following talks with the Rossoneri about a potential transfer this month, the decision has been taken to delay transfer discussions until the end of the season.
Udinese were said to be seeking as much as €25m (£22m) for the midfielder, but the Serie A club have now decided that they could get an even higher transfer fee in the summer.
Whether the Gunners would enter that bidding war for Jankto, it remains to be seen. The Czech is a left footed creative midfielder, having scored five goals and contributed six assists in 21 games this season.
Considering Arsenal already have a similar player in Jack Wilshere in the squad, a lot may depend on whether the England international signs a new contract to extend his stay at the Emirates beyond the end of the current campaign.
