Nicolas Otamendi and Eliaquim Mangala are technically the ideal central-defensive partnership.
Otamendi is a tough, aggressive, front-foot defender, who is often keen to get tight to his opponents and win back possession in higher areas.
Whereas Mangala may still be far from the finished article, but he has the pace to provide effective cover in behind and his natural game is more as a sweeper on the back foot.
The balance of the pair is much better than if Otamendi was partnered with like-minded City skipper Vincent Kompany or Mangala was positioned alongside Martin Demichelis.
Therefore, news that Otamendi has recovered from an ankle injury suffered in the 2-1 victory over West Brom to line up in the second leg of his side’s Champions League quarter final with Paris Saint-Germain must be considered good news for their chances of reaching the semi-finals.
Previous matches this season when Otamendi and Mangala have started together brings equally good news. The Citizens have won two-thirds of fixtures with this pairing, compared to barely half with an alternate defensive duo.
This includes eight straight victories at the Etihad and so suggests that the 33/20 that City beat PSG in the second leg is a tad overpriced.
However, digging a little deeper into the Otamendi-Mangala partnership highlights an even more attractive betting proposition for the Champions League showdown.
Manuel Pellegrini is yet to see his side keep a home clean sheet in any competition this term when the Argentine and Frenchman have been picked in tandem.
Given that the French champions have only failed to score in two road trips all season – at Real Madrid and Angers – expecting PSG to net at least once looks sensible.
It is 10/3 that City win a game in which both teams find the target and this looks the best path to profit in this quarter final second leg.
