Celtic ended the 2018/19 Scottish Premiership campaign with a 2-1 win against Hearts after securing their eighth consecutive league title with victory over Aberdeen two weeks ago.
The Hoops have the chance to win their third consecutive domestic treble next weekend when they face Hearts once again, this time in the Scottish Cup final, as they look to end the season on a high.
Celtic face a slightly uncertain summer with the ongoing speculation over who will be named as the next permanent manager at Parkhead, with a number of names being linked with the job.
Whoever will be in charge next season will no doubt be looking to strengthen the Hoops’ squad in an attempt to win all there is to win in Scotland once again in the 2019/20 campaign and take Celtic further in Europe.
Here we take a look at a number of players from the Bundesliga who the Hoops could look to sign this summer.
Drmic has featured just five times for Borussia Monchengladbach this season, scoring twice, and the Switzerland international is out of contract this summer.
Toljan has had a relatively inconsistent time on loan at Celtic after his January move, but given Mikael Lustig’s uncertain future at the club, the Hoops could look to pursue a move for him again this summer. At 24-years-old, the full-back has time to improve after a slightly unconvincing loan spell.
Walace has been linked with a move away from Hannover 96 following their relegation from the Bundesliga this season, and the defensive midfielder would be a solid signing for the Hoops.
Ayhan has had a fine season for Fortuna Dusseldorf and has been linked with a move away this season. The versatile defender could be the perfect replacement for Bundesliga-bound Dedryck Boyata.
Knoche could also be identified as a replacement for Boyata, and the centre-halve is another who had had a good campaign in the Bundesliga for Wolfsburg this season.
Mateta would be a fine signing for the Hoops following his standout campaign for Mainz. The striker scored 14 goals in the Bundesliga this season and would add to Celtic’s firepower up-front.
Szalai is another who is out of contract this summer, and the striker would add further height to Celtic’s strike force at 6ft 3′.
