For the first time since they were promoted to the Premier League in 2011, Swansea are in a proper relegation battle.
They currently sit 17th in the Premier League, and have only scored 20 goals all season, only Aston Villa have less. Andre Ayew has been the Swans' key man in attack this season and they can't let him join relegation rivals Sunderland.
Despite starting the season so well, Swansea have only won three times in the league since the beginning of October.

The Swans scored seven goals in the opening four league games, as Ayew and Bafetimbi Gomis ran riot in an impressive beginning to the campaign.
Gomis scored in every one of those four league games, but has only scored one goal since. With Swansea's complete lack of investment over the last couple of seasons, it looks unlikely that they will go out and buy another striker, especially given that Charlie Austin is no longer on the market.
This makes it even more important they keep hold of Ayew. Since joining on a free transfer from Marseille in the summer, the Ghanaian has been Swansea's best player. He has the pace and power not only to create goals, but to score them too, while he is also capable of playing in any of the three positions behind the striker.
Ayew is the Welsh side’s top goal scorer in the Premier League with seven goals, although with only four other players finding the back of the net it is no surprise to see them struggling. If they are to have any hope of staying in the division, he cannot be allowed to leave the Liberty Stadium.
He certainly can’t be allowed to join Sunderland, having already sold Jonjo Shelvey to another club in danger of relegation in Newcastle.
Sunderland themselves have struggled in attacking areas this season, with Jermain Defoe the only man scoring on a consistent basis for the Black Cats.
At Sunderland, Ayew would certainly strengthen the side, as he would create chances and find himself on the end of a fair few. Swansea would desperately suffer without him, and would be among the favourites for relegation.
With Ayew in the squad, Swansea have enough quality to comfortably remain in the division. However, if he were to move up north to Sunderland, the Swans would have an almighty task on their hands.
