A return to Arsenal on Wednesday night will be an "emotional" occasion for Thierry Henry, the man named the club's greatest ever player following his move to Barcelona.Henry twice won the Premier League during his time with the Gunners and became the club's all-time record goalscorer in a hugely successful eight-year spell in North London.But the forward was pitted against a number of old friends when Barcelona were drawn to face Arsenal in the Champions League, with the first leg of the quarter-final coming at Emirates Stadium on Wednesday night.Henry may well be left on the bench by Pep Guardiola having struggled with his form at Barca this season, but the striker who remains a self-confessed Arsenal fan is anticipating a "special" occasion."I'm very emotional, but also staying calm," Henry said. "It will be a strange game for me. Before the draw I said that I did not want to face Arsenal. That was my wish. But now that's the game we've got and we'll have to give everything."It's very special. To return home is strange and even more so in the quarter-finals of the Champions League. It will be different because I spent seven years at Highbury and only one at the Emirates, but to see the people, the fans and the other employees at the club again will be very strange.
