VERSUS
Both Arsenal and Chelsea should be familiar with one another. After all they have already met 3 times this season with Arsenal coming out on top 2-1 in all three previous encounters. However the champions league is a different kettle of fish from the english premier league and this tie may proove to be very tight.
Key Battles
versus
Patrick Veira vs Frank Lampard;-
The midfield area in any football game is crucial and games are won and lost here. In Patrick Viera Arsenal have one of the most highly rated and reputed midfield enforcers in the world. His awesome athletisism, strenght and power have made him one of the forces of european football. Viera has a huge influence on his team and when he is on song his team will follow suite. Therefore in order for Chelsea to stop Arsenal from building up a head of steam they will have to stop Viera. This job will definately be handed to Frank Lampard one of the revelations of the season so far. Lampard combines a good work rate with skill and technique. His midfield forays also enable him to grab his fair share of goals. However he will need to use all his ability to prevent Arsenal and in particular Viera from dominating the midfield in what could prove an extremely important battle.
versus 
Thierry Henry vs John Terry;-
Le King has been in breathtaking form this season. He is arguably the best striker in the world and undoubtedly the quickest. This season has seen Henry become the leading scorer in the premier league and his form in europe has not been too bad either. The landmark hat-trick in the San Siro against Inter sent shock waves round europe. In Henry Arsenal have an almost perfect striker. His pace and skill give the team an extra dimension and these are undeniably the two characteristics that defenders hate. It is highly likely that John Terry will be appointed with this dreaded task. One of the form players at the moment Terry is one of the reasons why the Chelsea has built up a reputation as being one of the moist solid defences around. His strenght in the air,sense of positioning and playing of the ball out of defence are all excellent. In addition Terry is also regarded as the natrual replacement of Rio Ferdinand in the Englan defence. However it remains to be seen wether or not he will be able to compensate for a lack of genuine pace with his great sense of anticipation. If not Henry could run riot.
