Pervis Estupinan is back at work with the Albion squad as they target the new season.

The Ecuador left-back was shown undergoing tests on the return to training.

He has missed the current Copa America due to an ankle operation and is expected to return some time into the coming Premier League campaign.

Jack Hinshelwood, James Milner and Kaoru Mitoma, who all missed the later stages of last season due to injuries, also featured in a short video from the training complex in Lancing, released by the club.

Among those players undergoing tests were returning loanees Andrew Moran, Marc Leonard and Mahmoud Dahoud as well as new signing Ibrahim Osman.

Leonard is known to be of great interest to several EFL clubs after again impressing on loan at Northampton.

He was shown in conversation with assistant coach Andrew Crofts.

Dahoud failed to adapt to the Prem last term and went on loan to Stuttgart, were he also had little impact.

He showed glimpses of his talent on the ball last term and it remains to be seen what part he can play in the plans of new boss Fabian Huerzeler as he also arrives from Germany.
