According to "Mancini: Diary of a Champion", a new book to be published next week:
* During the January transfer window, Liverpool made "tentative enquires" about the possibility of swapping Carroll for Tevez.
* To facilitate the swap, the club was willing to take a £10 million hit on the deal and drop Carroll's valuation to £25 million (the valuation placed on Tevez by City at the time).
In a press conference at the time, Mancini was cagey over the possibility of any Tevez-Carroll swap deal:
"At the moment no because we have not talked about this with Liverpool. This is a new one for me. I never heard of this. Carroll is a good player...but it would be difficult and I don't think [it is going to happen]. There was no phone call to me.
Manchester City clearly new better, and the deal fell through. Soon after, I ran a poll asking whether Liverpool fans would be happy if the club signed Tevez. Over a 5000 fans voted in the survey, and the results showed that 63% of voters would happily accept Tevez at Anfield. A surprising result to say the least.
Just imagine if that swap deal had gone through; it's entirely possible Liverpool's league form would've improved, and perhaps the club would be in the Champions League spots right now.
Of course, there's no guarantee Tevez would've made any difference, but he grabbed 4 goals and 2 assists in six starts after being brought back into the fold by Mancini, which is the same number of league goals/assists Carroll has managed all season (!)
As much as I'm not a fan of Tevez, It would he hard to turn down that particular swap deal.
