Having lost the spearhead of their attack in Wilfried Bony to the Africa Cup Nations and then Manchester City, now Swansea must contend with the league leaders coming to the Liberty Stadium.
Without in a win in their last four in the Premier League, Garry Monk will be desperate to get a good performance from his side, with the hosts priced up at 5/1 for victory.
Meanwhile, Chelsea come into this contest having written the wrongs of their recent defeat at White Hart Lane with victories over Watford and Newcastle respectively, with the Blues offered up at 4/7 to pick up three points here, and the draw at 3/1.
Mourinho’s men look all set for another win, but there are a trio of bets that look better value than the straight victory.
As was established against Tottenham, the Blues are nowhere near as solid at the back away from home as they are on their own turf.
In fact 84% of the league goals they have conceded this year have come away from the confines of Stamford Bridge.
Nevertheless, the absence of Wilfried Bony takes a lot out of Swansea, and in their current form the Welsh outfit cannot be backed to avoid defeat.
But with both teams finding the net in the Swans’ last four, this looks a juicy price.
This is becoming a favourite here at Ladbrokes News, and the stats put this as a pure value bet.
Chelsea have scored two or three goals in six of their last eight, and 14 of their 21 Premier League matches in 2014-15.
So with a 66% success rate, the value of this bet at 11/10 (implying a 47% chance) is obvious.
The Brazilian-cum-Spaniard netted a hat-trick when these two met in west London back in September and is has shown some of the form we all know he is capable of lately.
After his blistering start to the campaign, he went through a relative lull, going four games without finding the net.
But with three in his last five, he looks to be coming back to his best, and can highlight that by bagging at least a brace in south Wales.
