Chelsea welcome returning hero Drogba

Chelsea FC welcome Galatasaray AŞ and their former goalscoring hero Didier Drogba to Stamford Bridge for the second leg of their round of 16 tie, which is level at 1-1 after the first game in Istanbul.

• Drogba was part of the Chelsea side that won the UEFA Champions League for the first time in 2011/12, scoring a late equaliser and then the decisive penalty in the final shoot-out against FC Bayern München in Munich on 19 May 2012. That was the Ivorian's final kick for the club.

• This season Chelsea made up for their 2012/13 disappointment, when they became the first UEFA Champions League holders to fail to survive the group stage. That early exit was the only blot in 12 otherwise consecutive qualifying campaigns; this term, the Blues won their group for the eighth time in that period.

• José Mourinho masterminded Chelsea's sole round of 16 defeat between 2006/07 and 2011/12, against an FC Internazionale Milano side also featuring Wesley Sneijder in 2009/10.

• Although they reached the second group stage in 2000/01 and again the next year, Galatasaray's only past experience of the round of 16 came last year when they beat FC Schalke 04 4-3 on aggregate. The home leg ended 1-1, Burak Yılmaz opening the scoring. Hamit Altıntop and Burak were on target in the away match, substitute Umut Bulut firing the winner.

Previous meetings
• The teams have met on one previous occasion, the 1999/2000 UEFA Champions League group stage. Chelsea won 1-0 at home, Dan Petrescu (52) scoring against opponents who lost goalkeeper Claúdio Taffarel – now part of Galatasaray's coaching staff – to a 30th-minute red card. The Blues triumphed 5-0 away.

• The lineups at Stamford Bridge on 28 September 1999 were:
Chelsea: De Goey, Ferrer, Leboeuf, Desailly (Høgh 63), Petrescu, Morris, Wise, Ambrosetti (Poyet 72), Babayaro, Sutton (Flo 85), Zola.
Galatasaray: Taffarel, Popescu, Arif Erdem (Mehmet Bölükbasi 31), Okan Buruk (Emre Belözoğlu 72), Fatih Akyel, Ümit Davala, Hagi (Hasan Şaş 73), Ergün Penbe, Hakan Ünsal, Hakan Şükür, Capone.

• Chelsea met Turkish opposition in the 2007/08 quarter-finals, winning 2-0 at home to Fenerbahçe SK – Frank Lampard on the scoresheet – after a 2-1 reverse in Istanbul. In the 2003/04 group stage, they lost 2-0 at Stamford Bridge against Beşiktaş JK, triumphing by the same scoreline in the away game at the Arena AufSchalke in Gelsenkirchen, Germany.

• After Beşiktaş's victory, Chelsea established a long unbeaten run in home group fixtures which extended to 29 games (W22 D7) before FC Basel 1893 prevailed at Stamford Bridge on matchday one this season.

• Galatasaray have not won in eight visits to English clubs, drawing three and losing five. Overall their record is W3 D8 L7.

• The closest they came to victory was in the 1993/94 UEFA Champions League second round. Having trailed 2-0 early on, Cimbom led Manchester United FC 3-2 at Old Trafford midway through the second half, only for Eric Cantona to conjure an 80th-minute equaliser. Their away goals proved crucial in taking the Süper Lig side through after the home leg ended 0-0.

• In 1999/2000 Galatasaray beat Arsenal FC 4-1 on penalties after the UEFA Cup final in Copenhagen had finished goalless after extra time, becoming the first Turkish team to win a UEFA competition.

Match background
• Chelsea, looking to pick up a European trophy for a third straight year after capturing the UEFA Champions League in 2012 and the UEFA Europa League in 2013, topped Group E by a two-point margin from Schalke despite home and away defeats by Basel. They won all four other fixtures without conceding a goal, downing FC Steaua Bucureşti 4-0 away and 1-0 at home and Schalke 3-0 home and away.

• Chelsea have won six and drawn one of their seven home games in European knockout rounds since a 1-0 loss to Manchester United in the 2010/11 UEFA Champions League quarter-finals.

• Mourinho, who has landed the UEFA Champions League with both FC Porto (2004) and Internazionale Milano (2010), is bidding to become the first manager to win the European Cup with three different teams. Only Bob Paisley (Liverpool FC 1977, 1978, 1981) has collected the trophy three times as coach.

• Galatasaray lost their first Group B match 6-1 at home to Real Madrid CF, Roberto Mancini subsequently replacing Fatih Terim as coach and overseeing a draw at Juventus in his first game on matchday two. Despite away reverses against FC København (0-1) and Madrid (1-4), the point would prove crucial as the Turkish side defeated Juve on matchday six through Sneijder's late goal to finish runners-up in the section.

• In UEFA competition Chelsea have lost the tie twice on the six occasions they have drawn their first leg away from home, most recently against FC Barcelona in the 2008/09 semi-finals (0-0 away, 1-1 home). Those four aggregate victories came after a 1-1 away draw, most recently against Liverpool in the 2007/08 semi-finals when they prevailed 3-2 at home after extra time.

• Galatasaray have won just two of the ten European ties in which they have been held at home in the first leg, thrashing OFK Beograd 5-1 in the second instalment of the 2010/11 UEFA Europa League third qualifying round after a 2-2 draw in Istanbul and overcoming Schalke at this stage of last season's competition (1-1 home, 3-2 away). That was the first time they had advanced after a 1-1 home draw, after four successive aggregate defeats.

• Drogba was at Chelsea between 2004 and 2012 – playing under Mourinho from June 2004 to September 2007 – and scored 100 goals in 226 top-flight matches. He also won three Premier League titles, four FA Cups and two League Cups.

• Emmanuel Eboué represented Arsenal between 2005 and 2011, playing alongside Ashley Cole from 2004 to 2006.
