Everything was going well for Chelsea boss Frank Lampard on the injury front, but that quickly changed.
After a couple of matches with a full bill of health, two of his wingers picked up hamstring injuries in very quick succession.
Timo Werner and Christian Pulisic
There is no doubt that the first choice option will be Christian Pulisic and Timo Werner as the starting wingers.
Werner has mainly played on the left this season, however he has struggled of late to find the back of the net, while Pulisic has struggled with injury problems himself.
