#4 Toni Kroos
It’s fair to assume that one of Bayern Munich’s biggest regrets in the transfer window in recent history is the sale of Toni Kroos to Real Madrid.
The talented Germany international had been tipped to replace Bastian Schweinsteiger once he had moved on from Bayern Munich but after just one season under Pep Guardiola, the Spanish giants came calling.
With three Bundesliga and DFB Pokal titles to his name, Kroos was part of the team that lifted the Champions League in 2013 but after 24 goals and 49 assists in 205 games, it was time to move on.
“My change of team was correct, in fact, from my point of view there is no doubt about it. Clearly, if you go abroad to a top club, it means one more step in your development,” Kroos told the German FA in 2017.
The Germany international had spent just one season under the tutelage of Pep Guardiola before swapping Bavaria for Madrid in 2014. The move was announced just days after Germany had lifted the World Cup in Brazil while his €25 million switch could well be the steal of the century.
In his time at Madrid, Kroos has lifted the league title on one occasion but perhaps what is more impressive is lifted the Champions League on two successive occasions.
