The Wales international produced fantastic form at Euro 2016, starting all six of his country’s fixtures whilst providing tenacity and playmaking quality in the middle of the park.
But the 26-year-old’s Liverpool future remains shrouded in doubt with his Anfield contact due to expire at the end of next season and little suggestion of talks over an extended deal.
Nonetheless, The Telegraph claim the former Swansea City star is incredibly in demand, with his former employers, Southampton, Sevilla and three more clubs reportedly targeting him for a summer transfer.
The Saints have been drawn to Allen as a potential replacement for Victor Wanyama, who moved to Tottenham Hotspur in an £11million move earlier this summer.
However, Swansea have already seen a bid rejected by Liverpool, who reportedly quoted the Welsh side an £11million price-tag.
