Said ACL CEO's Daniel Gidney to the club website: "Oasis are one of the biggest ever bands not just in this country but throughout the world.
"We are absolutely delighted that Liam and Noel Gallagher will be performing in Coventry and this is a major coup for the Ricoh and the city.
"The Enemy were a massive hit with the crowd when they played here earlier this year and it will be fantastic to see them play in the stadium bowl at the Ricoh this time.

"Having Oasis and The Enemy on the same bill means this is going to an unmissable night.
"We have worked really hard to entice music promoters to the Ricoh Arena and securing this Oasis date means we are firmly established on the map. They are, without doubt, once of the biggest bands in British music history.
"We will have a limited number of tickets to sell at the venue and we expect tickets to sell extremely quickly so I would advise everyone to buy their tickets early to avoid any disappointment.
"This is going to be the biggest concert of 2009 in the Midlands - and it is happening at the Ricoh Arena."
