Should Emery be looking at Barrenechea and Barry?

The final part of our Q&A with BBC Sport football reporter Nick Mashiter focuses on potential player recalls.

Charlie asked: Why do you think Unai Emery has never called Enzo Barrenechea back to Villa Park to give him the opportunity of impressing this season - especially being in the Europa League? He has show real maturity, consistency and promise in both Spanish and Portuguese leagues, plus Europe, and I would have loved to see him in a claret and blue shirt.

Nick answered: Brought in along with Samuel Iling-Junior as Douglas Luiz went the other way to Juventus last year, I think most Villa fans would have liked to have seen what Barrenechea could produce.

The same could go for Iling-Junior after he helped England Under-21s win the European Championship in the summer, instead of allowing him to go to West Brom on loan.

Neither have made an appearance for Villa and Barrenechea never will, given he needs one more game for Benfica to trigger a permanent move for about £10m.

We could look at it cynically given his previous loans and upcoming transfer mean Villa have made a profit on the £6.9m he cost from the Old Lady.

The deal went through as Villa - and others - looked to take advantage of a PSR loophole as clubs looked to be essentially swapping players: Tim Iroegbunam and Omari Kellyman going out as Lewis Dobbin and Ian Maatsen came in from Everton and Chelsea respectively.

But Emery is a fine judge of a player. If he felt Barrenechea would make the grade at Villa Park, he would have kept him.

And finally, Prit asked: Given the constraints of PSR and the lack of competition for Ollie Watkins as a striker, should Emery bring back Louie Barry and give him a season as a Villa striker rather than let him fester on endless loans? After all, it is the cost-effective solution?

Nick answered: There was a sense, internally, last season Barry was not going to make the grade long-term at Villa Park and loan spells - to maximise his value if and when they decide to sell - would be the best option.

He may have scored 15 goals at Stockport County in the first half of last season - many of them spectacular - but Villa wanted to see him arriving in the box more, making late runs and getting into the right position.

He was unlucky to get injured when he joined Hull City in January, making just four appearances which halted any momentum from his time at Edgeley Park.

Now, in a struggling Sheffield United team, he is getting good experience but is that enough to see him come and back up Watkins? I would suggest not and it feels it would be too big a step.
