No offense to your friend Ricky, but seems to me the dealings of the true owners of Tevez have been a bit shaddy, so not surprised that owners wanted to think it over before commiting.
Also, while I think Tevez would be great, and at 22 mill an expensive but good buy, not sure he's top of the list for Rafa, or at least not part of the plan he shared with the owners months ago. He's an opportunity buy, but if he does end up going to Italy, not necessary a big opportunity lost.
Personally I think they put on the brakes to see if the Spainish players who I'm sure have been on the shopping list for a while, pan out. If not, Tevez would be a great option if still available.
This seems to line up with what the owners are reported to have said today about spending on the plan, but not spending like a drunkin sailor. While Tevez would have been great, and maybe still an option, don't think they wanted a spur of the moment purchase.
