Celtic are working to tie Stephen Welsh down to a new contract after handing him his debut last week, Football Insider can reveal.

The defender, 20, returned to Parkhead last month after his season-long loan to Championship outfit Morton was terminated early.

A Celtic source has told Football Insider the club are keen to keep Welsh and convince him his future lies in the east end of Glasgow.

Welsh’s contract, which was signed in March 2018, is due to expire at the end of the season.

Manager Neil Lennon has personally held talks with the youngster, who is regarded as capable of establishing himself in the first team in the future.

He was handed his Hoops bow against Hamilton Academical eight days ago and responded with an impressive 76-minute display as part of a three-man defence alongside Kristoffer Ajer and Christopher Jullien.

Welsh was an unused sub in the 4-0 thrashing of Motherwell last Wednesday and was not involved in yesterday’s Scottish Cup win over Clyde as he is cup-tied from earlier in the campaign.

The versatile defender is mainly a centre-back but he often filled in at right-back for Morton in the first half of the campaign.

He made 18 appearances for the second-tier outfit, 15 of which were league starts and most of them on the right side of defence.

Welsh has been capped by Scotland at Under-19, Under-17 and Under-16 levels, with 22 caps overrall at the age groups.
