After his sublime performance against Chievo Verona, there was a lot of talk about Balde Diao Keita. The Spain-born Senegalese forward scored a goal and logged an assist in the game, earning Man of the Match and plenty of plaudits.
It wasn't the first impressive showing from the 18-year-old in a Lazio shirt. The former Barcelona player has shown flashes of brilliance in the league and in Europe, but against Roma he showed why it would be hasty for the Aquile faithful to expect too much too soon.
Before being replaced by Stefano Mauri, Keita was anonymous for much of the game and looked very much like a teenager out of his depth.
Games like this provide every young player with invaluable experience, and it would be unfair to judge him by the same standards as you might a fully developed player. But there is a danger that he might be expected to make a serious senior contribution too soon at Lazio, either because people choose to trust in his obvious potential or because the club's limited budgets mean that there simply isn't enough quality elsewhere to make a difference.
For the player's sake, let's hope he gets more time.
