According to numerous reliable reports, Arne Engels's proposed switch to Nottingham Forest is off, with the midfielder now set to stay at Celtic. Despite strong links and advanced talks, the transfer has broken down. It's a setback for Nottingham Forest, who had hoped to strengthen their squad in a key position before the deadline. With negotiations ending unsuccessfully, Arne Engels will not join Nottingham Forest - but interest from Leipzig could yet reignite. Nottingham Forest are only scoring 1.0 goals per game (24 in 24) this season, which suggests they need more creativity in the middle. Arne Engels would be seen as the link to raise the tempo and feed the attack. Celtic continue to be linked with Benjamin Arthur, Joel Mvuka and Kasper Hogh while Nottingham Forest are also rumoured to be tracking David Moller Wolfe, Luca Netz and Robin Gosens.
