Dinamo Zagreb boss Zoran Mamic has confirmed that Chelsea have submitted an offer for young goalkeeper Adrian Semper, according to reports from the Express.
The Blues have launched a £3.1million bid after sending representatives to scout the 18-year-old, but Dinamo have no interest in selling the shot-stopper.
However, Mamic has claimed that while it was hard for the club to turn down such a large proposal for a young player, he sees Semper as an important asset for the future despite his age.
“Chelsea representatives have been in Zagreb, where they have prepared a great offer,” the Dinamo coach said.
“They were professional and pleasant people, but we said no. It is never easy to reject such a big offer for a young player.
“But we are convinced Adrian has a fantastic future ahead of him and we want him to spend at least some of that future with Dinamo.
Earlier in the season, Chelsea were desperately looking to sign a goalkeeper amid a knee injury to number-one goalkeeper Thibaut Courtois, with no real back-up for summer signing Asmir Begovic until the signing of Marco Amelia.
Begovic luckily did not add to their injury woes, and although Courtois is back to full fitness, it seems the Blues hierarchy are looking for a long-term successor to the Belgium international by monitoring Semper’s development.
Semper was involved in Under-17 World Cup for Croatia last summer in Chile, losing to finalists Mali in the Quarter Final.
