That Bulka was our first choice prior to Petrovic and he went to Saudi and did his ACL!
One thing is for sure though, all 3 had excellent numbers in terms of crosses claimed, so that was a key focus for us, the same as Alderete on aerial duels won in the box.
We allow the opposition to have the ball out wide as opposed to centrally and with that, we allow a lot of crosses, as statistically you are far less likely to score from a cross then a central position (only 1 in every 80 odd crosses results in a goal or similar), so buying a goalkeeper who is excellent at claiming them makes a lot of sense.
Smart, logical recruitment.
