#7.Centre Midfielder – Thiago Alcantara
Now this must be the biggest regret on the list. Why on earth did FC Barcelona get rid of Thiago Alcantara? The Spanish midfielder seemed like he would be a part of the side for a decade but his 2013 move to Bayern Munich surprised everyone. The Spaniard came through La Masia and broke into the first team in 2009 but failed to really hold down a starting place. Perhaps the club shouldn’t have re-signed Cesc Fabregas as the former Arsenal man seems to have hampered the progress of Thiago. Regardless, the midfielder signed for Bayern Munich in 2013 under Pep Guardiola and has since won three Bundesliga titles with the club.
