Arsenal defender Mertesacker knows Van Persie Euros clash with be decisive
Mertesacker is eagerly anticipating Germany's clash against Holland on June 13, but admits it will be a novel experience to see Van Persie as an opponent rather than a team-mate.
"We are looking forward to seeing each other at the tournament," he said. "He is our skipper [at Arsenal] and I always try to support him, but then everything changes.
"It is very, very strange to be opponents but as a footballer you have to cope with these situations and I look forward to seeing him."
