Celtic were linked with Carlos Mane last summer and he remains available. Should they make a move this time around?

Celtic will be looking for a new wide player this summer with Patrick Roberts set to return to Manchester City.
One player who is already on their radar is Portuguese winger Carlos Mane, who the Daily Record reported they registered an interest in last summer.
Mane signed with German side Stuttgart instead, who have been playing in the Bundesliga II this campaign after a surprise relegation.
The Sporting Lisbon owned winger has had a productive season, scoring six goals and providing seven assists in 19 appearances.

His campaign is now over after he sustained a knee injury a fortnight ago, but Portuguese newspaper Record report it is not viewed as serious enough to require an operation, indicating he will be fresh and raring to go next season.
The Daily Record reported last year that Mane could be available permanently for as little as £4 million, making the winger an inexpensive gamble, and one who would fit into Brendan Rodgers' price strategy.
Stuttgart are on course to secure promotion to the Bundesliga, but Mane is a long term target of Celtic and his form could be enough to tempt them into renewing their interest.
Last summer he was quoted by the Scottish Sun admitting he would be open to a switch, commenting: "Celtic? I would not say no."
Health permitting, he would be a logical target for the Scottish champions to try and improve next season.
