He told The Times: "At a time when we didn't have endless economic resources, I think that we made good signings in general. We should be talking about players like Reina, Agger, Mascherano, Xabi Alonso, Luis Garcia, Torres, Babel, Lucas Leiva, Skrtel and also Arbeloa, Sissoko, Fabio Aurelio, Kuyt. These are players who have brought a lot to the team. And in certain cases – for example, Sissoko and Bellamy – the club gained financially.
"We have signed 28 players in four years for the first team. Considering that the number of changes we had to make when I arrived and the fact that without much money we have to take more risks, I don't think this is a disproportionate number."
Benitez also compared his spending with Liverpool's nearest rivals.
"Chelsea had spent £120 million previously and an additional £240 million to win the league in the 2004-05 season. Manchester United have spent £200 million in recent years. This year on Carlos Tevez, Owen Hargreaves, Anderson and Nani, that cost them more than £70 million. Tottenham have spent £100 million in the last two seasons alone. And Arsenal have spent more or less the same amount as we have on young players with potential.<>
"In my four years at Liverpool we have spent £150 million and we have gained somewhere in the region of £70 million. Looking at those numbers, there's a difference of £20 million per season, yet we have won four [trophies] and played seven finals. When all things are considered, that's not a bad return. I think that we're on the right path."
