It's not the same at all.
Wolfsburg would be Everton or Spurs level in the bundesliga comparative to size of other clubs in their league etc. We've seen Everton and Spurs cosy up to bigger prem clubs in the past. Look at Moyes giving Rooney to the rags. Over the years he got Howard, Neville, Gibson and others on the back of that deal...heck he even got himself a job he wasn't qualified for. That's how business is done. I've no problem with Wolfsburg posturing to gain favour with Bayern as one day they'll no doubt want a Bayern cast off.
Liverpool could learn a thing or two from Allofs, otherwise we'll stop sending our cast offs their way. ;-)
