Munich - After missing out on the business end of FC Bayern München's historic treble-winning campaign through injury, Toni Kroos resurfaced as one of the key components in Pep Guardiola's 2013/14 remould.

With domestic honours coming out of his ears and the FIFA 2014 World Cup in full swing, bundesliga.com felt it was high time you got to know Bayern's unsung midfield hero a little bit better...

Kroos began his career at hometown club Greifswalder FC. In 2002, aged 12, he joined former Bundesliga outfit Hansa Rostock, playing in the youth team coached by his father. The midfielder's natural talent did not go unnoticed and in the summer of 2006, Greifswald's most famous son was on his way to FC Bayern.

After just a year in the youth ranks, Kroos made his Bundesliga debut under Ottmar Hitzfeld on 26 September 2007. As well as chipping in with two assists for Germany international striker Miroslav Klose in an eventual 5-0 win over Energie Cottbus, he also became, temporarily at least, the youngest player (17 years, eight months and 22 days) ever to don Bayern's famous red shirt - an accolade that now belongs to Danish hotshot Pierre Højbjerg (17 years and 251 days, 13 April 2013).

Despite making exceptional progress in the Bavarian capital, Kroos' search for regular playing time took him to Bayer 04 Leverkusen on an 18-month loan deal during the 2008/09 winter break. It wasn't until the following season, however, that the budding midfield talent really came into his own under the tutelage of none other than Jupp Heynckes, notching nine goals and 12 assists in 33 appearances.

In January 2010, Kroos was called up to the senior Germany team for the first time, making his debut in a friendly against Argentina on 3 March 2010, before being selected for Joachim Löw's 23-man squad for the FIFA 2010 World Cup in South Africa. He took his World Cup bow in Germany's final group match against Ghana, replacing club team-mate Bastian Schweinsteiger in the 80th minute and made further appearances as a substitute against Argentina, Spain and in the third-place play-off against Uruguay.

Bronze medal in hand, Kroos returned to Munich where he soon registered his first Bundesliga goal for the club in a 4-1 win over SC Freiburg on 29 October 2010. Holding down a place in midfield alongside Schweinsteiger, the former Leverkusen man went on to make 49 appearances in all competitions in his first full season back with his parent club.

Kroos' stock continued to rise in 2011/12, but for the Bayern collective it was another disappointing campaign, punctuated by a penalty shoot-out defeat to Chelsea FC in the final of the UEFA Champions League - and on home soil at that. The midfielder later travelled to Poland and Ukraine for EURO 2012, where Germany fell prey to Italy in the semi-finals.

Undeterred, the 24-year-old played a decisive role in helping Bayern assert their treble-winning muscle in 2012/13, racking up twelve goals and delivering eleven assists in 46 outings in all competitions, before a groin injury sustained against Juventus FC in April 2013 ruled him out of Bayern's final seven games of the campaign, as well as the Champions League and DFB Cup final.

Kroos has made quite the impression on new head coach Pep Guardiola, underlining his importance to the club by playing in all but one of Bayern's 30 competitive outings so far in 2013/14, but according to SV Werder Bremen youth team coach Dieter Eilts, there's an even "better Kroos" out there in the form of Toni's younger brother Felix (right), who also came through the youth ranks at Hansa Rostock. He is yet to match his brother's achievements, though, scoring just once in 24 appearances for current club Bremen.

Rumour has it that young Toni missed around 40 days of school during the academic year that preceded his big city move to Munich. "He knew what he wanted and was always a lot more focused than the rest," said former teacher Sieglinde Heimann. "He was pretty good at biology - I even copied off him," added an old classmate. "I returned the favour in maths and physics."

Kroos' 'you scratch my back, I’ll scratch yours' approach to schoolwork didn't deter his female peers, who were even swooning over the burgeoning Bayern star in his mid-teens. "They liked him, sure, but I wasn't aware of him having a girlfriend,” a fellow student told die Welt. Sorry to disappoint you ladies, but Toni's off the market nowadays: his long-term partner Jessica Farber (right) gave birth to a boy, Leon, last August.
