BELGRADE (Reuters) - Shakhtar Donetsk, RB Salzburg and Sheriff Tiraspol edged closer to the lucrative Champions League group stage after beating their respective opponents in the first legs of their playoff-round ties on Tuesday.

A Pedrinho goal gave Shakhtar a 1-0 win at Monaco while Salzburg fought back from a goal down to beat Brondby 2-1 at home as Karim Adeyemi and Brenden Aaronson cancelled out Mikael Uhre's opener for the visitors.

Sheriff staged the shock of the night with a 3-0 home rout of Croatian champions Dinamo Zagreb in a bid to become the first Moldovan team to reach the group stage of Europe's premier club competition.
