MADRID (AP) — Atletico Madrid brought back Diego to strengthen its Spanish league title push, while Valencia witnessed a series of arrivals and exits from the club as the January transfer window closed on Friday.

Atletico signed the Brazilian midfielder on loan from Wolfsburg until the end of the season. Diego previously played under coach Diego Simeone during the 2011/12 season, helping Atletico win the Europa League title that season.

Valencia is looking to turn around a bitterly disappointing season that has left it 17 points adrift of the Champions League places.

The club unloaded a handful of underperforming players — including Argentina midfielder Ever Banega — and added several recruits, including former Barcelona midfielder Seydou Keita.

Barcelona, which is co-leader with Atletico, and Real Madrid did not make any last-ditch transfer moves.
