Andy Carroll returned to training for West Ham on Friday following a three-month lay-off – and Hammers fans on Twitter are expecting that he won’t be fit for long.

The 27-year-old suffered a knee injury during his side’s Europa League clash against Astra Giurgiu in August.

Slaven Bilic revealed in October that the injury was originally expected to see him out for “four to six weeks.”

However, it has now taken him 13 weeks to return to training with the Manchester United fixture on Sunday probably coming too soon for the powerful forward.

Now West Ham fans have welcomed back the striker on social media, but some are wary that he may return to the treatment table soon.

Here are a selection of their messages on Twitter:

Carroll returned from knee surgery in September 2015, which had seen him miss seven months of football for the Hammers.

He then suffered a fresh hamstring blow in January during the 3-1 victory over Bournemouth, which saw him spend a month on the sidelines.

He has built up a reputation for being injury-prone, but since his £15million move from Liverpool in 2013 he has scored 16 goals in 68 fixtures, establishing himself as a good striker for the club.

The east London outfit will welcome the return of Carroll, as they sit in a lowly 17th place.
