Chelsea do not fear any backtracking from Portugal coach Luiz Felipe Scolari.

Scolari had asked for the announcement to be delayed until after Portugal's interest in Euro 2008 was over.

But with speculation rife, it was agreed yesterday Chelsea could confirm the appointment if Portugal beat the Czech Republic.

Scolari has yet to sign a contract with the Blues.

But his camp are adamant he will not renege on this deal - like when he changed his mind over taking the England job two years ago after giving the FA his word.
