Borussia Monchengladbach is sorry to hear of Lionel Messi's groin injury.
It means he will miss Barcelona's Champions League game at Gladbach next week.
The Bundesliga club have wanted to send a message of support to the 29-year-old, wishing him a quick recovery:
"What a shame! We would have loved to have you on Wednesday with @FCBarcelona and to see you at BORUSSIA-PARK. Get well soon, Lionel Messi #UCL #BMGFCB".
