Crystal Palace have signed Newcastle United winger Andros Townsend.

The England international has agreed a five-year contract at the club, and his £13 million transfer comes on the same day Dwight Gayle has moved in the opposite direction.

"I'm extremely delighted," the 24-year-old winger told Palace's official club website.

"I had chats with the manager (Alan Pardew) and chairman (Steve Parish) before I signed and I'm pleased to be part of Crystal Palace's future.

"By the sounds of things it's going to be a bright one and I can't wait to get started."
