Two names immediately spring to mind with Manchester United's capture of Edinson Cavani. One is Zlatan Ibrahimovic, the other being Radamel Falcao.
One had a transformative impact during Jose Mourinho's first season. The other floundered, scoring only four goals in 30 games. There is certainly a sense of intrigue as to how close Cavani's time at Old Trafford veers towards either of them.
United hope, of course, he is more aligned to Ibrahimovic's first year at the club. An elder statesman, whose character dragged the team through games, pulled the youngsters with him.
