In's latest stats review, we look back on a week that saw a legend return to London, a Norwegian youngster reaffirm his potential and trophies handed over to Atletico Mineiro, Bayern Munich and CSKA Moscow.

100 English Premier League goals and 157 overall are the Chelsea tallies that Didier Drogba will be aiming to top up after last week agreeing a move back to the Blues. The 36-year-old is returning after brief stints with Shanghai Shenhua and Galatasaray - "he just went for a short holiday," said Jose Mourinho - and will be hoping to make his way up the London club's all-time scoring list. As it stands, only three players in Chelsea's history have scored more than Drogba, and the Ivorian re-signed just as the man who tops that particular list moved elsewhere. Frank Lampard, who scored 211 times in 13 seasons at Stamford Bridge, is now looking forward to a new adventure in Major League Soccer after becoming the fourth player to commit himself to the fledgling New York City FC franchise.

15 is the age at which Martin Odegaard became the week's youngest goalscorer. The Stromsgodset prodigy scored the opener in a 3-1 win at Sandnes Ulf that ended a three-game losing streak for Norway's reigning champions. Odegaard, who has trained with both Bayern Munich and Manchester United, made history earlier in the year by becoming the Tippeligaen's youngest player and scorer. This latest goal was his third in the top flight, but while it returned Stromsgodset to winning ways, they are facing an uphill battle to retain the title. After all, they remain nine points behind an impressive Molde side that has strung together 21 matches unbeaten, a run that dates back to 5 April.

6 Russian Super Cups have now been won by CSKA Moscow after the capital club retained the trophy on Sunday. Leonid Slutski's team came from behind to win 3-1 against FK Rostov, the Russian Cup winners, who ended the match with just nine men. The victory cemented CSKA's traditional dominance of the tournament, and of cup competitions in general. Indeed, while the Russian champions still trail city rivals Spartak in league titles, they have won more Russian Cups (7) than any other team - and have three times as many Super Cup triumphs as their closest challengers: Zenit, Rubin Kazan and Lokomotiv Moscow, all of whom have two. Spartak, meanwhile, have yet to win this competition, although they will be hoping to rival CSKA for the country's biggest prize when the Russian Premier League season gets underway on 1 August.

3 goals in two days from Robert Lewandowski propelled Bayern Munich to victory in the Telekom Cup in Hamburg over the weekend. The pre-season tournament saw the former Borussia Dortmund striker make the perfect first impression, with a superb solo goal against Borussia Monchengladbach on Saturday followed by a brace in the following day's 3-0 win over Wolfsburg. With five goals overall, having scored twice for Dortmund in a previous edition, Lewandowski is the highest scorer in the history of the Telekom Cup. His goals also helped Bayern become the first team to retain the trophy since the competition's inception in 2009.

2 extra-time own goals from Lanus handed Atletico Mineiro their first-ever Recopa Sudamericana title in a dramatic second leg on Thursday. The Belo Horizonte outfit had been 1-0 up from the first leg in Argentina and looked on course to settle the tie in 90 minutes, with the scores locked at 2-2 going into injury time. Lautaro Acosta had other ideas though, and silenced the premature celebrations of the Estadio Mineirao crowd with a goal that necessitated an additional half-hour of action. However, extra time proved disastrous for Lanus, with Gustavo Gomez and Victor Ayala - who had earlier scored at the other end - putting through their own goal, and Acosta earning a red card for dissent. The 5-3 aggregate win not only secured O Galo's first Recopa Sudamericana, but maintained Brazil's recent dominance of a tournament that pits the winners of the Copa Libertadores against the Copa Sudamericana champions. Each of the last four editions have now ended with different Brazilian champions, with Atletico following in the footsteps of Corinthians (2013), Santos (2012) and Internacional (2011).
