Reigning Amlin Challenge Cup Champions Harlequins are relishing being back in the top flight with Director of Rugby Conor O'Shea echoing Eric Elwood's sentiments about going head-to-head yet again.
"This is what the players and supporters wanted - to be back in the Heineken Cup and playing against the best teams.
"It was great winning the Amlin Challenge Cup last season and the experiences of beating London Wasps, Munster and Stade Francais Paris in the knock-out stages will stand us in good stead on our return to the Heineken Cup.
"Connacht are old favourites with us and we played them in the Pool stages last year and know just how tough it is to go to Galway.
"We know Gloucester very well and how difficult they are to beat, and Toulouse are the aristocrats of European rugby, they boast the best record of any side in the tournament and it will be fantastic to face them again."
