West Ham boss Gianfranco Zola believes Arsenal counterpart Arsene Wenger is wrong to claim the Premiership's quality has slipped.

Zola said: "The Premier League is getting better, the level has gone up.

"Teams now are so well tactically prepared than when I first came to England to play.

"Before it used to be only a few clubs who were prepared but now, whoever you play, it is very difficult. Every team is well-organised making it very tough no matter who you play. It is tough for everybody."
