Brendan Rodgers has made an already strong Celtic side even harder to beat, in his time in Glasgow and is now busy trying to improve his squad to compete with the best in Europe. But he might also lose a few first-team stars this summer and one such player who is extensively linked with an exit is Stuart Armstrong.

With just a year left on his contract, Armstrong is yet to put pen to paper on a new deal and is reportedly now a transfer target for PL clubs like Crystal Palace. He is valued at just £4m, will be an absolute bargain and might attract more suitors this summer. So how can Celtic replace him? Here are three players the Celts should look to sign to replace the 26-year old:

Marko Grujic (Liverpool):

The Serbian international is yet to kick off his Liverpool career but spent a season on loan in the Championship, where he helped Cardiff City with some consistent performances. However, he has not returned to Anfield and is no closer to a place in the first team next season under Jurgen Klopp. So it might be best for all involved that he goes out on yet another loan spell and Celtic could be the decent destination this time around. He can certainly be a first team star at Glasgow and could be an effective signing for Rodgers this summer.

Joe Allen (Stoke City):

The Welsh international worked closely with the Celtic manager in their time at Liverpool but Allen was sold to Stoke City by Klopp, a couple of years ago. But the midfielder has now dropped to the Championship, with Potters failing to avoid the drop last season. Allen fits into Rodgers’ style of play perfectly and will actually be an upgrade on Armstrong, thanks to his experience in the English top flight. He may also be cheap, now that the Potters are relegated and is definitely a player Celtic should look to sign.

James Morrison (West Bromwich Albion):

The 32-year old was one of the most experienced midfielders in the Premier League last season and he was used sparingly by West Brom. The Baggies had a season to forget as they were relegated to the Championship and Morrison might now be tempted to join a new club and start afresh. He made just four appearances in the English top flight last season, but at 32 still has a couple of years left in him and could be a decent acquisition for Celtic.
