Striker Keigan Parker is out of favour at Blackpool

Despite averaging almost two goals a game, Swansea may add another striker with Keigan Parker one possibility.

The Scottish frontman, 25, is out of favour at Blackpool and will also be out of contract next summer.

"We've been following Keigan Parker since the game we had against Blackpool (last season)," Martinez told the BBC.

"He performed really well on the day and we've kept our eye on him, as well as another 200 or 300 players that I could mention!

"We're never going to stop speculation...but overall we're going to bring people in that are better than what we've got.

"If not it's pointless and at the moment the players that are here are making it very difficult to find better players."

Whether Swansea move for Parker is complicated by the situation surrounding Warren Feeney.

The Northern Ireland international has impressed with six goals in 14 games since joining on loan from Cardiff.

Feeney's loan spell ends on 1 January and Swansea are interested in a permanent move.

But he will be out of action for the next six to seven weeks with an ankle injury and also the financial problems Cardiff face in court could complicate any deal.

A 4-1 romp over visiting Cheltenham on Boxing Day kept the Swans top of League One, but they face a sterner test on Saturday when promotion rivals Leeds come to the Liberty Stadium.

"Leeds are a very, very strong side as we all know and it's going to be a glamorous occasion," Martinez added.

"We're looking forward to it, it's a sell-out and it's one of those days that the fans really deserve.

"We've got fantastic links throughout our history with Leeds United, we need to be ready but enjoy the occasion."
