Manchester City manager Manuel Pellegrini was left concerned over the fitness of in-form striker Alvaro Negredo as his side swept into the Capital One Cup final with a 9-0 aggregate win over West Ham.
• Brewin: City demolition job
City won 3-0 at Upton Park to follow their 6-0 thrashing of the Hammers in the first leg at the Etihad.
Negredo scored a double -- adding to his hat-trick in the first leg -- but had to have treatment following a challenge from James Tomkins late in the game. The striker carried on, but Pellegrini said he would have to wait until Wednesday to determine the seriousness of the knock.
"Alvaro Negredo has a problem with his shoulder," the City boss told Sky Sports. "He just has a pain at the moment, and we will see, hopefully tomorrow.
"It was a very professional performance. It was easy to think the game was finished from the 6-0 in the first leg, but it was important to reach the final winning all the games. Wembley is always important."
For West Ham counterpart Sam Allardyce, injuries to Joe Cole and Mohamed Diame -- who was stretchered off in the closing minutes -- rounded off another miserable night.
"The most disappointing thing was our defensive unit doing what it did in the first few minutes," he said. "Manchester City are a super, super team but it was not a super, super opening goal.
"It was bog-standard defending, which was disappointing. You cannot make mistakes at this level to the amount we did. The killer of all was the injuries to Joe Cole, who should not be out for so long, and Mo Diame, which looked really serious."
