Adam Lallana has admitted that he feels "frustrated" by his first season at Liverpool due to numerous injuries and a lack of playing time.

The England international's career at Anfield got off to a disappointing start when injury struck during pre-season.

The midfielder has scored four goals since, but his momentum was broken when he picked up a groin problem during the Reds' 2-1 defeat to Manchester United in March.

Speaking about his first season at Liverpool, Lallana told TheFA.com "It's not gone great. It started off with injury and I've had another over the last few weeks with a few more in between. It's been quite frustrating if I'm being honest and I haven't been out on the pitch as much as I'd have liked.

"Getting injured and missing pre-season I feel played a big part in my recurring injuries - it's a very important part for a footballer to get the basis of the fitness in, but I want to be fully fit for the run-in."

It is not yet known whether Lallana will be fit for Sunday's FA Cup semi-final against Aston Villa at Wembley.
