Swansea City and Chelsea are goalless at the break in tonight's Capital One Cup semi-final second leg at the Liberty Stadium.
The Swans still hold a 2-0 aggregate lead over the Blues following their triumph at Stamford Bridge two weeks' ago.
Chelsea were appealing for a penalty as early as the seventh minute, but Demba Ba was adjudged to have run into defender Ben Davies.
Swansea came close to breaking the deadlock on the night soon after as Michu forced a low save from Petr Cech.
Chelsea were soon forcing the issue at the other end, only for Gary Cahill's header from a corner to be cleared off the line by Davies before Ramires's effort was held by Gerhard Tremmel.
The visitors were soon dominating, but some poor touches in the final third kept the scores level.
