Arsenal's Petr Cech sends message on Twitter to Cristiano Ronaldo

Ronaldo Strikes

Arsenal star Petr Cech congratulated Cristiano Ronaldo on a historic achievement.

Arsenal goalkeeper Petr Cech has offered his congratulations to Cristiano Ronaldo after the superstar reached a career milestone.

Ronaldo netted the 500th goal of his career as Real Madrid in an away clash to Swedish side Malmo in the Champions League.

It was a terrific achievement for the former Sporting Lisbon and Manchester United star.

Cech reached out to him on Twitter to nod to the opponent he once faced in a Champions League Final, and has also come up against at international level.

It was Cech's first message on Twitter this Champions League week, the the goalkeeper staying diplomatically silent on Arsenal's result.

The former Chelsea goalkeeper was controversially left on the bench by Arsene Wenger, with stand-in David Ospina going onto make errors as the Gunners suffered a shock 3-2 home defeat to Olympiakos, to leave their Champions League chances in real jeopardy.

With two successive losses in the competition, the chances of Cech facing Ronaldo in the group stages at present look thin.
