Swansea City striker Wilfred Bony will be sidelined for several weeks after suffering a hamstring injury in the Europa League defeat to Valencia.
Bony had to be replaced by Alvaro three minutes before the half-time interval, having pulled up clutching his thigh after chasing a long ball.
This news has certainly caused Michael Laudrup an offensive headache ahead of Sunday's Premier League clash away against Manchester City, with Alvaro and 21-year-old Rory Donnelly the clubs only attacking options.
This bad news comes after hitman Michu was ruled out for six weeks in the beginning of November with an ankle injury picked up in the Swans' 1-0 defeat to fierce rivals Cardiff City.
The Swansea boss said: "It could be quite a serious one. We'll have to wait two or three days until we get a scan but unfortunately we are talking several weeks."
"it is a blow but thats is how it is. You have to accept it and when you have a lot of games this is a possibility.Let's see what happens with Michu in a week or two."
The Welsh club have eight fixtures during December, including crucial games with other teams around them such as Aston Villa, Newcastle and Hull. That might prompt Laudrup to consider bringing in another striker during the January transfer window.
It has been reported that Danish manager is weighing up a loan move for Liverpool winger Raheem Sterling, who has recently fallen out of favour at the club.
However it is not all bad news for Laudrup ahead of the clash against City with defender Angel Rangel, who had to be withdrawn at the death with a calf problem, joining in training this morning.
"Angel had a problem with his calf but hopefully it isn't too bad," he added.
