Barcelona might be interested in Mohammed Kudus these days. However I don't think they would be free to sign new players in January according to the La Liga financial rules. They just need to sell unnecessary players in the team to raise some funds. They aren't in need of any transfer now as they already have a very qualified squad.
Besides it is said that Kudus is more eager to sign for a Premier League team rather than the others.
Rumors are circulating that Barcelona are interested in Mohammed Kudus and when Barcelona manages to get Mohammed Kudus it will be a good opportunity to strengthen the midfield line which may still be less good than the Barcelona side, so they are more trying to get Mohammed Kudus in the transfer market that will be will open in early 2023.
I noticed this Ajax youngster was playing well on world cup so it's only a matter of time he left Ajax and moved to bigger clubs and no wonder if Barcelona want him because during playing in Ajax he has upgraded his skill and performance and after being an promoted from Jong Ajax gradually Kudus has became an key players from Ajax and 9 goals during this season in all competitions proven he is very talented player and unfortunately Barcelona is not alone who want him because Liverpool, Tottenham and Everton has joined the race to gets him even there is speculation AC Milan is the closest teams who will gets him this winter
