Monday was transfer deadline day in the UK and across the major European leagues.

However, Portugal and Netherlands was Tuesday, Austria is today and Turkey is 11 February and Czech Republic is not until 22 February.

The key one is UEFA. Clubs have until 11pm tonight to register their squads for the play-off and knockout stages for European competition.

All clubs are permitted to register three new players. It does not matter if they have already played in the tournament they are being registered to play in.

Aston Villa signed four experienced players – Marcus Rashford, Axel Disasi, Marco Asensio and Donyell Malan. One of them will miss out.

Manchester City also signed four, although given Vitor Reis’ relative inexperience, he seems more likely to be the odd one out than Abdoukodir Khusanov, Omar Marmoush and Nico Gonzalez.

Chelsea only signed Mathis Amougou on loan from St Etienne but they left Cole Palmer, Romeo Lavia and Wesley Fofana out of their Conference League squad in the first place.

They are the clubs with an issue.
