Arsenal players returned from their off-season to join up with new boss Unai Emery’s first training session recently, and the new kit and manager wasn’t the only interesting thing that was to be seen at London Colney.Players not involved with the World Cup - mercifully we had a low number of our squad flying out to Russia with their respective nations - started pre-season, resplendent in the new training kit and full of smiles for the many cameras at Arsenal’s training ground.There was much to see for us fans who have been starved of any Arsenal for what seems like an age, and one or two of these images and videos picked up a forgotten face or two.Chief among the players who have returned from season-long loans to the first team fold is fan favourite and boyhood Gooner Carl Jenkinson. The England defender spent last campaign on loan at struggling Birmingham City, but it was a terrible year for Jenks, who dislocated a shoulder and was out for the majority, only picking up seven appearances.It was in stark contrast to his loans at West Ham the two seasons before, and it means that the right back’s future at Arsenal is far from certain, and much will depend on pre-season and if he impresses Emery and co.It could be worse though, he could be Cohen Bramall. the young wing-back had an even worse loan at Birmingham City, but not through injury. He could not force himself into the first team fold, and upon returning to Arsenal, Bramall didn’t join up with the first team squad, and trained with the Under-23’s. Bramall hasn’t had much of a chance to impress, but with Monreal and Kolasinac ahead of him in the pecking order, Bramall must show his worth this summer.Another who showed his face at Colney was Emi Martinez, and the stopper fared little better on loan last season. He made just 3 appearances on loan at La Liga side Getafe, and the Argentinian goalkeeper must surely be looking at a move to progress his career, with Bernd Leno coming into the Arsenal fold.There will be more than a few players leaving Arsenal this summer, so keep them peeled on The Arsenal Review for the latest ins and outs at Arsenal.
