Chelsea interim manager Frank Lampard faces at least three major team selection decisions for the Blues' decisive clash against Real Madrid in the Champions League this evening. For his first game back in temporary charge, Lampard opted to deploy a back four with Kalidou Koulibaly and Wesley Fofana as the centre-back pairing.
Thiago Silva, who has missed the last six weeks with a knee injury, could come straight back into the starting XI given his importance to the Blues, despite only taking in part one training session. There is also a major debate over whether or not Lampard should deploy a back five in Spain.
One of Chelsea's best defensive performances came in the Champions League last-16 second leg against Borussia Dortmund. In that game, Reece James, Fofana, Koulibaly, Marc Cucurella and Ben Chilwell were deployed as the back three and wing-backs with the Blues winning 2-0.
