  Compelling evidence for a new form of matter has been claimed to be formed in
Pb+Pb collisions at SPS. We critically review two suggested signatures for this
new state of matter: First the suppression of the J/$\Psi$, which should be
strongly suppressed in the QGP by two different mechanisms, the color-screening
and the QCD-photoeffect. Secondly the measured particle, in particular strange
hadronic, ratios might signal the freeze-out from a quark-gluon phase.
