About this part, fans would like to buy a player who will *surely* be a starter for the next 10 years.
But, realistically, what are the chances that we will find a player who will fit to our team perfectly, and who will cost a decent amount of money?
For example, Barca has a horrible history of CB signings in the last 15 years.
We had huge problems to find players who will fit in, and a lot of them looked perfect on a paper.
For example:
1999': Dehu from Lens, French ligue winners from 1998.
-- Dehu played 11 matches in Barca career
2001: Patrick Andersson, experienced Swedish NT player from Bayern Munchen
-- he was here for 3 seasons, he suffered horrible injuries
-- played 19 matches in 3 years
-- transfer price 8 Millions back in 2001. That is like 20+ M for a 30 years old today
2001: Christanval, 22 years French young Cb from Monaco
-- price 15 M
-- that is like 30-40 M today (a young player with lots of potential)
-- played 31 match in 2 years
-- released for free, if I remember correctly
2003: Marquez, 5,2 Millions from Monaco, 24 years old, something like 15M today
-- he was a success in Barca staying and playing for 7 seasons
2006: Thuram, 34 years old Cb from Juventus
-- price 5 M Euros, something like 10M for a 34 years old today
-- stayed for 2 seasons with average success
2007: Milito, 17 Millions, like 35 M today
-- suffered horrible injuries
2008: Pique
-- a huge success
2008: Caceres, 21 years old, 16,5 M, like 35-40M today
-- didn't succeed here
I won't even mention Henrique
2009: Chygrynskiy, 22 years old, 25 M. something like 50M today
-- didn't make it here
2014: Mathieu, 20 M
Vermaelen 10-20 Millions
So, let's do some maths here:
-- our only successful Cbs in the last 15 years were:
1. Puyol, from La Masia
2. Pique, from La Masia and Man. Utd
3. Marquez, a transfer
4. Mascherano, who is not a Cb at all
If we remove Puyol and Pique from these stats, since they are our products, let's see how many transfers we attempted in the last 15 years, and what is our success ratio with those transfers:
Success:
1. Marquez, 15M in current prices
Failure:
1. Chygrynskiy 50M
2. Christanval 40M
3. Caceres 35M
4. Mathieu 20M (not a failure, but...)
5. Vermaelen 10M
6. Thuram 10M
7. Dehu
8. Henrique
Injuries:
1. Milito, 35M
2. Andersson, 20M
So, our success ratio with foreign defenders is 1 out of 11 in the last 15 years (only Marquez was a good job, and we had 2 players with horrible injuries in Andersson and Milito).
Also, we attempted high-profile signings of young defenders a few times also: Chyngrynskiy 50M, Christanval 40M, Caceres 35M, Milito 35M (in the current transfer-market prices).
What I am trying to say, when people say: we should buy a guy for the next 5-10 years, well, a history is saying that it isn't such an easy job.
I am not saying that we shouldn't buy a young Cb for a 50M, but I can easily see Laporte or Marquinos as the next Caceres or any of these players from above.
