Celtic are highly interested in signing Dominique Heintz from Bundesliga team SC Freiburg as Postecoglou aims to sign the German defender.

As we understand, Ange Postecoglou has already started his own scouting regime and called in favours to all his former staff and friends regarding potential targets.

The 27 year old defender has made 21 league appearances for SC Freiburg and he’s rated highly by their manager Christian Streich who would want to hold on to all his key players.

However, we can confirm that Celtic are in direct contact with the German club about a possible £5 million offer, the Bundesliga club are eager to get top value for Heintz.

Our sources at Bulinews have stated that Celtic are prepared to make an offer of £3 million upfront and the rest to be paid in instalments, a sell on clause could be added as Freilburg know how good Celtic are at selling players on for profit.

There will be numerous rumours in the press over the coming weeks and this is simply one of those that we have been told.
