Villarreal midfielder Robert Pires admitted this week that his former Arsenal teammate was unhappy at Barca.

The Sun says Henry's unrest is likely to trigger a wave of interest in Europe's top clubs - including the Premier League's big guns.

However, there is no way he would return to Arsenal where he is regarded as a legend - because boss Arsene Wenger has moved on and is rebuilding his team around strikers Emmanuel Adebayor and Robin van Persie.

Henry cost Barcelona £16million when he was sold by Arsenal last summer.

The Frenchman was linked with Liverpool earlier this season.
