Leeds United, Celtic and Newcastle have until Saturday to trigger the £4 million release clause in Sebastian Andersson’s Union Berlin contract, according to Kicker.

As Union director Olivier Ruhnert told BZ last week, ‘everyone knows’ that one of the most influential forwards in the Bundesliga can be snapped up for a bargain fee this summer.

What his many suitors might not have been aware of, however, is that there is an expiry date on that release clause.

And, as Kicker points out, The Iron Ones will be able to demand far more than £4 million for their star man once the working week is over.

The same publication reported last month that Andersson is a target for a goal-shy Newcastle, newly-promoted West Brom, Bournemouth, Brentford and reigning Scottish Premiership champions Celtic.

Leeds are another interested suitor and, while the 28-year-old Sweden international might not initially look like the kind of technically gifted, nimble footballer Marcelo Bielsa likes, it is no coincidence that the Argentine’s sides are at their best when lead by an ‘old school number nine’.

Think Patrick Bamford at Leeds, Fernando Llorente at Athletic Bilbao, Andre-Pierre Gignac at Marseille.

Andersson, at 6ft 3ins, is a massive threat at set-pieces – perhaps the one area where Leeds are anything less than exemplary.

Seven of his 12 Bundesliga goals across 2019/20 were scored with his head.

But if Leeds, Celtic, West Brom and co are serious about Andersson, then they have no choice but to trigger that £4 million clause before Saturday or risk paying a much larger fee.
