Dominic Solanke’s struggle for regular game-time at Liverpool is becoming an increasing concern for the England hierarchy.

Aidy Boothroyd, the England under-21s manager, has admitted Solanke’s failure to earn more opportunities under Jurgen Klopp could damage his hopes of an international future.

Solanke, the former Chelsea attacker, is highly regarded by Football Association officials and received a confidence boost on Tuesday when he was invited to train with Gareth Southgate’s senior squad.

But he is yet to feature in any of Klopp’s 18-man squads for Liverpool so far this season and it is understood England are worried that his development is being affected.

Southgate claimed last week that England face the prospect of losing “exceptional players” who are not playing regular competitive football.

And ahead of the under-21’s game against Holland on Thursday, Boothroyd has also weighed into the debate by revealing his fears over Solanke.
