I really liked what I saw from him in the Iran game in particular. By the account of ITK, it does seem that we're at least looking at him. However, he doesn't have a great disciplinary record as someone pointed out on SC. In 28 performances in all competitions, he received 11 yellows and 3 reds (two of those soft). It's possible Poch could get him to chill, but he's also at a club with an academy of coaches renowned for their individual development coaching.
If this is a problem at this stage (24) and with coaches proven in player development, I'm not sure how he'd fare under the increased pressure of the Prem. This could very well be why such a versatile and talented player is still playing at Sporting Lisbon at 24 years old and only made his jump to Europe through Russia.
