Champions League last eight: the strengths and weaknesses of Europe's big guns

Champions League quarter-final draw in full:

ARSENAL

Wellbeing: Arsenal have been in flying form in recent weeks, with the winter break serving the Gunners well. Indeed, their only defeat in their last 10 came in the first leg at FC Porto last month, though they had the last laugh having progressed to the last-16 on penalties on Tuesday night. Currently top of the table, albeit only on goal difference, Mikel Arteta's side are one of the form teams in Europe and having welcomed back key men in recent weeks; are well positioned to maintain a silverware push in the next couple of months.

Can't do without: Mikel Arteta's men are flying and you could pick out any number of first-team regulars as the star turn at present. However, it is hard to look beyond Martin Odegaard. The centre-backs, starboy Bukayo Saka and Declan Rice are all deserving of plaudits but Odegaard is the man to knit the team together. Having endured a sub-par opening few months to the campaign as Arsenal adjusted to life without Granit Xhaka, their skipper has proven he is the player they need to keep fit.

Unsung hero: Key for Arteta has been keeping his core players fit this season. Injury to Oleksandr Zinchenko may have derailed Arsenal's pursuit of glory, particularly as that coincided with Jurrien Timber and Takehiro Tomiyasu's spell on the sidelines. Jakub Kiwior may have struggled at left-back when called upon earlier in the campaign yet has been in flying form in recent weeks in the role. Previously viewed as fourth-choice left-back, the Polish defender has excelled since the turn of the year and deserves to continue in this watertight backline.

Sting in the tail: Arsenal's youthful squad has certainly drawn admirers across the continent but
