Chelsea have received an injury boost as John Terry returns to training ahead of their vital Champions League match against Porto, Daily Mail reports.
The 35-year-old was recently struggling from an ankle injury which saw him miss games against both Tottenham Hotspur and Bournemouth.
Terry was not expected to make a return so quick, but was seen training on Saturday as well as two additional times as he is now in line to feature against Porto.
Manager Jose Mourinho could decide to partner his club captain with Kurt Zouma in defence after Gary Cahill was criticised for his performance against the Cherries.
Mourinho knows that must pick up all three points against their upcoming opponents in order to ensure progression into the round of 16.
His side are now top of Group G, level on points with Porto, but have a far superior goal difference heading into the fixture.
However, if they lose and Dynamo Kyiv manage to win, the current Premier League champions could then be knocked out.
