The Welsh midfielder has not received any assurances of regular first team football next summer and is expected to complete a transfer soon.
The likes of Swansea, West Ham and Stoke are apparently interested in the player and the latest name in the list of suitors is Manchester United.
Apparently, Jose Mourinho is looking to sign the Liverpool midfielder this summer and he could be a replacement for the likes of Schweinsteiger. The German international has been linked with a move to Turkey.
A transfer from Liverpool to Manchester United is highly unlikely because of the rivalry between two clubs and the fact that Allen is unlikely to get much game time at Old Trafford either.
