Sky Sports pundit Paul Merson praised Brighton's transfer window and gave them a B+ grade for their January business.
The Seagulls brought in forward Jurgen Locadia from PSV Eindhoven for a club record £14m fee and striker Leonardo Ulloa returned to Albion on loan from Leicester.
Merson said: "They've brought in Leo Ulloa and I really like him. He scores goals and had a good record at Leicester, so I think that's a good deal. It's good to see they're having a go."
Merson gave his highest rating, A+, to Chelsea, Liverpool - who signed Virgil van Djk and received £146m for Philippe Coutinho - and Manchester United, who brought in Alexis Sanchez.
His lowest grade went to Bournemouth, with an F, after the Cherries did not sign a player in January.
