Manchester City could use defender Matija Nastasic as bait to beat rivals United to the signature of Bayern Munich midfielder Toni Kroos, [football] direct news understands. As FDN revealed earlier this season, the Bavarian giants have been monitoring the progress of the 20-year-old defender after a recommendation from talent scout Michael Tarnat, who used to play for the Blues. Club spies have attended City games and watched the Serbia international in action, and Bayern have been encouraged by the fact that Nastasic is no longer a first-team regular at the Etihad Stadium, boosting their chances of landing him. Sources close to both Manchester clubs have informed FDN that Kroos is a summer transfer target but City have the advantage of owning a player coveted by the European Cup holders. A cash-plus-player bid is on the cards, with the title challengers hoping a reasonably modest fee will be considered, due to the fact Kroos has little more than a year left on his contract at the Allianz Arena.
