Magnusson said: “We bought five players in January and sold none, so the squad is too big at the moment.
“For sure, Alan has to decide if he wants to sell and to bring some others in, to change the group a little bit – but it’s totally up to him.
“Alan still has my support. I have been impressed with him for many years now.
“We played quite well against Chelsea last week and showed in the first half we can compete with the very best.
“They are all good players at the club.”
