Abstract The J/ψ production in 158 A GeV Pb-Pb interactions is studied as a function of centrality. Its pattern, after a first sharp variation around E T =40  GeV , continues to fall down and exhibits a curvature change around E T =90  GeV . This trend excludes any conventional hadronic model and is in agreement with a deconfined quark-gluon phase scenario.
