Former Swansea manager Garry Monk has backed Jonjo Shelvey to thrive at Newcastle after his £12million January move.

The club decided to sell Shelvey to their relegation rivals just a month after sacking Monk, who had worked with the midfielder as both player and manager.And speaking onGoals on Sunday, he said Newcastle could see the best of him because he will enjoy playing in front of a packed St James' Park every week."Jonjo was a big part of what I did there and, of course, that consistency with him is what you're looking for," Monk said."You forget how young Jonjo is. He's got his peak years ahead of him and I think, once he learns that consistency in his game, you'll see what he can do. "He needs to be performing every single week and feel importance as a player. Newcastle will probably give him that."Garry Monk"He's got that magic ability to be able to pick passes. He canbe a match-winner. That's the key, but he needs to get that consistency in his game."I'm sure going to a club like Newcastle in front of that many fans and that type of club will suit him."A lot to do with Jonjo is motivation. He needs to be performing every single week and feel importance as a player. Newcastle will probablygive him that."It will be interesting to see. I'm sure he will go there and do well."Monk also spoke about his own departure from the LibertyStadium in December following a run of one win in 11 Premier League matches.He insisted he could have turned things around, but sayshe respected the decision of Swansea chairman Huw Jenkins.
