LEANDRO TROSSARD has been told that tonight’s game is the ONE to win.

The Belgian forward, a summer buy, could keep his starting place from the draw with Wolves when Albion renew their rivalry with Crystal Palace.

It will be his first taste of the always eagerly-anticipated showdown and he says he has been filled in on what to expect at Selhurst Park.

He said: “I have just been told that it is a derby and it is the only game in the season you need to win.

“That is the only thing I know about it, not much more.”

What Trossard does know is that the Seagulls will have to overcome a hostile atmosphere and a Roy Hodgson side in a decent run of form with no defeats in the last three games.

Belgium international Trossard said: “They are a good side and they have a lot of good players, so it will be a tough game there.

“They (the fans) are also very close to the pitch, so that will make it tougher.

“Everything put together will make it tougher. The crowd will be behind them and we have to deal with it.”
