Seattle Seahawks head coach Pete Carroll has criticised the Allianz Arena playing surface as a 'nightmare' after the NFL Germany game against the Tampa Bay Buccaneers.
The Seahawks lost their first game since September, winning four on the bounce before being taken down by Tom Brady and the Buccaneers, who were able to shut down the Seahawks impressive running game.
Rookie running back Kenneth Walker has been a revelation this season, but was unable to impress in Germany, as he, and a number of offensive players on both sides of the ball, did not look comfortable on the playing surface.
