Striker Marcus Haber has been offered a possible return to St Johnstone after being invited for a trial at the club, Sky Sports reports. The former loanee was with the SPL side last season, but returned to parent club West Brom after suffering a serious knee injury last November. Now the 22-year-old has been asked back to McDiarmid Park to earn a permanent contract at the club. The Baggies have not activated their 12-month extension option on his contract, meaning Haber is now available on a free transfer. Manager Derek McInnes has invited Haber to join his squad's pre-season trip to Iceland. And the Saints manager also hopes to finalise further deals shortly. He told The Courier: "There is a good chance one or two players will be coming in over the next week or so. "Marcus will join us in pre-season so we can have a look at him. He has recovered fully from the injury he received playing for us. "He is back home in Canada just now working on his fitness and playing charity and bounce games." McInnes is keen to add more new faces to his squad, but says he has found himself priced out of deals so far this summer. "Sometimes we have just had to say no because they are just too expensive," he explained.
