Frei is set to train with Liverpool.

Stefan Frei has been given permission by MLS club Toronto to make a temporary move to Liverpool, to train with the side during the American league's off season.

The 25 year old, who moved from Switzerland to the USA as a teenager, has starred for Toronto, making 81 appearances for the club since 2009.

And while many clubs in England have shown interest in the keeper, Liverpool are keen to take him on for a trial period to see how he shapes up alongside some of the Premier League's best.

"This is a great opportunity for Stefan and we were happy to give him permission to train with a historic club like Liverpool," Toronto manager Aron Winter told the American side's official website.

"He has emerged as one of the top keepers in the league since the start of his career and has certainly earned this special opportunity."

Liverpool currently have Pepe Reina as the undisputed number one goalkeeper, with Brazilian summer signing Doni in the wings as a back-up. But with both keepers pushing 30, Kenny Dalglish is already starting to look to the future, and is also considering his relationship with Toronto over the possibility of swapping players.

Liverpool have an agreement in place with Uruguayan side Nacional to deal with one another first and foremost in terms of transfers of players. And the club are no doubt looking to make ties with more sides in the Americas as they aim to create a club with the best players in the world who can challenge for trophies once more.

The Reds took on New York Red Bull striker Juan Agudelo this week, and Frei will train with the club for a week also, just like his MLS compatriot.

Red Bull star Thierry Henry is also in England at the moment, training with Arsenal, while David Beckham will decide whether his next move is in his home country after his contract with LA Galazy ran out.
