LONDON, Aug 31 (Reuters) - Spanish champions Real Madrid and Barcelona got their Primera Liga campaigns off to the worst possible starts with opening weekend defeats.

Newly promoted Bologna spoiled Ronaldinho's debut for AC Milan by scoring a surprise 2-1 victory at the San Siro on the first weekend of the Serie A season in Italy.

SPAIN

Champions Real Madrid and Barcelona slipped to defeats in their Primera Liga openers on Sunday, as Atletico Madrid set the early pace at the top of the standings with a 4-0 rout of promoted Malaga.

Deportivo Coruna were 2-1 winners at home to Real thanks to headers from Mista and Alberto Lopo in each half, cancelling out Ruud van Nistelrooy's equaliser just after the break.

Real, who were without the unsettled Robinho, rarely looked like getting back into the match once they were behind in the second half.

Second division champions Numancia spoiled Pep Guardiola's league debut as coach with a 1-0 home win, after Mario scored early in the first half.

Atletico built on their midweek qualification for the Champions League group stage, hammering four past promoted Malaga, from John Heitinga, Diego Forlan (2) and Florent Sinama Pongolle.
