The Premier League champions were heavily linked with Belgian playmaker Eden Hazard earlier in the season, only to lose out to Chelsea's £32m offer. They also targeted former Arsenal striker Robin van Persie and Basque midfielder Javi Martinez, neither of whom wound up at the Etihad; the Dutchman transferred to Manchester United in a £24m deal and the Athletic Bilbao product joined German giants Bayern Munich. City were also rebuffed in their attempts to sign Roma midfielder Daniele De Rossi.
The 47-year-old former Lazio and Inter Milan boss, whose only signing up to deadline day was Jack Rodwell from Everton, went on a spending spree on the last day, signing Javi Garcia from Benfica, Matija Nastasic from Fiorentina, Scott Sinclair from Swansea City and Maicon from Inter Milan.
"I was frustrated, as it is difficult to do everything in one week or 10 days. When you finish the season, you have a meeting with the club. You talk about players but sometimes it is not possible to take all the players you want. You should have a different choice. But getting these players we have bought, I am happy," the Daily Mail quoted Mancini as saying.
As City's spending topped £40 million the total for the Premier League was a staggering £490 million and that excludes loan deals like Andy Carroll's move to West Ham. The average spend per club was £24.5 million.
