The England international is increasingly frustrated with the lack of opportunities he has been given since returning to Old Trafford last August and will not entertain the prospect of spending more time on the bench next season.
Hugo Lloris is entering the final year of his current contract this summer and Spurs have continued to monitor developments at Old Trafford, with manager Jose Mourinho a known Henderson admirer.
Less than a fortnight ago, Graeme Souness revealed to Sky Sports that Mourinho had told him he thought Henderson “should have been in the (United) squad a few years ago”.
But Henderson’s £ 120,000-a-week five-year contract, signed in August, could be a sticking point for Spurs.
As it stands, no discussions are underway to extend Lloris’ stay at Tottenham – one possible option being a move to Paris Saint-Germain and another chance to team up with former manager Mauricio Pochettino .
A United fan, Henderson’s preferred option is to stay at Old Trafford, but only as a No.1.
If that’s not an option open to him, it is understood that he would be open to the prospect of playing abroad – and Dortmund’s Champions League pedigree will only help their cause.
Ole Gunnar Solskjaer is increasingly aware that the fact that Henderson and David de Gea fight for the No.1 shirt next season would benefit neither the players nor his team.
With two years plus an additional 12-month option still on De Gea’s £ 350,000-a-week contract, a permanent move from Old Trafford seems unlikely for the Spain international at the moment.
But a loan move would prove more feasible if Solskjaer picks Henderson as his No.1.
