Liverpool have suffered a massive blow as their star midfielder Adam Lallana is set to be out of action for four weeks, according to the Daily Mail.

The England international was replaced in the 55th minute during the Reds' 2-2 draw against Leicester City on New Year's Day. He picked up a thigh injury, which forced Brendan Rodgers to withdraw him, and the Foxes scored twice in two minutes, soon after Lallana left the field.

The former Southampton star has been in fine form for the Merseyside club, scoring a brace against Swansea in Liverpool's 4-1 win and also managed an assist each against Bournemouth and Arsenal.

Liverpool plays Chelsea twice later this month in the two-legged Capital One Cup semi-final clash. Also, the Reds take on their local rivals Everton at Goodison Park in the Merseyside derby on 7 February.

With Lallana set to be out of action for a month, he will miss the Capital One Cup clash and his absence will be a major boost for Chelsea. It is likely that he will return for the Merseyside derby next month.

Lallana missed Liverpool's 2-1 FA Cup third round victory over AFC Wimbledon and the Northern Irishman admitted that his player will be out of action for a month.

"More or less, it might be a wee bit shorter than that. It's a slight strain that he has, so no real timeline on it, but hopefully it won't be as long as that," Rodgers said, when asked about Lallana.

Meanwhile, Rodgers has heaped praise on Steven Gerrard after the midfielder's brace helped Liverpool qualify for the fourth round of the FA Cup, where they will face Bolton Wanderers later this month.

"He was outstanding in the game, it was a brilliant individual performance from him and the real catalyst for us," Rodgers said.

"It was a tough game overall; we started the game quite well but then gave the ball away cheaply. In the second half, we were much better."

"He scored two and if he was a really selfish player, he might have stayed on the ball and got himself a hat-trick - but he was still trying to create opportunities for other players," he added.
