Everton suffered a cruel injury blow last night, with Mikel Arteta set for a number of weeks on the sidelines.
The Spanish star has recently started to tick for the Toffees, and admitted that his own individual performances has risen dramatically following a slow start to the season at Goodison Park.
Arteta's individual resurgence has coincided with an up-turn in fortunes for David Moyes' men, but the Scottish boss admitted that his star man now faces a spell on the sidelines.
"It looks like a hamstring injury. It's too early to say - I'm not sure but I'm guessing he will be out for a few weeks," he told the club's official website.
"It was a big blow for us because we needed some creativity and I knew that if we didn't have him, we would be struggling to create too much," Moyes said.
Everton fell behind at Goodison Park last night, with Jean Beausejour heading Birmingham into an early lead. John Heitinga smashed home an equaliser later in the first period, but the hosts were unable to find a winner in the second half.
"We didn't play well enough probably to win the game, but we had a few half-chances."
With Marouane Fellaini, Tim Cahill and now Arteta in the treatment room, Everton will be searching for some creativity in the coming weeks ahead of clashes against Fulham, Aston Villa and Wolves.
