Apparently Kagawa will only cost around £5 million? If that is all Dortmund are asking for then I'd be disappointed if we didn't at least make a go for him, wouldn't hurt to have another playmaker in the team with Rosicky into his 30s now. As for some of the other rumors, unfortunately Vertonghen would rely on us getting rid of Djourou + Squillaci and him being happy at 4th choice. Belhanda is thought to be PSG-bound but Giroud is a chance if, again, we get rid of Chamakh and Park. It looks like we'll add one of M'Vila or Javi Martinez but with both Manchester clubs said to be keen on Martinez, M'Vila is the more likely option.
Ideally I'd love to see us add Vertonghen, M'Vila, Kagawa and Giroud but at most we'll only get two of them. We'll probably have to bring in a new keeper as well with Fabianski likely to be let go/not extend his contract and Almunia is off anyway.
