Alan Smith is worried by Newcastle United's lack of depth ahead of the new season.
Magpies boss Kevin Keegan's preparations for the 2008/09 term have been hampered by the absences of a number of injured first-team players.
Keegan has so far added Jonas Gutierrez from Real Mallorca and Danny Guthrie from Liverpool to his squad, and has since revealed he is hopeful of landing further reinforcements this transfer window.
Smith, who featured in Newcastle's 1-0 pre-season friendly defeat to Doncaster on Saturday, admits he is concerned by the club's lack of first-team options with the new term on the horizon.
Smith told the Daily Express: "To see people missing in pre-season, that's the biggest worry. But if we can get all those players fit, it will make a big difference.
"Near the end of last season, we were fortunate to have just about all of our players fit and we put a decent run together. We need to get them right for the start of the season.
"Realistically, for this club, the top half of the table is a must.
"When you look around the dressing room the quality is there. But football now is more and more of a squad game, where the number of players at the club is important. At the moment, we have not got that available."
