Chelsea full-back Marcos Alonso is reportedly hoping to put pen to paper on a contract extension at Stamford Bridge after his resurgence under the German manager Thomas Tuchel.

The Spanish star was left out in the cold by former Blues chief Frank Lampard and had not featured since September before Tuchel arrived at the club last month.

But Marcos has been a regular feature in the new coach’s side, starting in five of his first seven matches in charge, and is thriving again in a left wing-back position.

The 30-year-old’s current deal isn’t due to expire until June 2023, but according to a recent report from the Sun, he is hoping to renew his deal by another year.

The report adds that Alonso was pondering over a possible transfer to another PL team or a switch back to Serie A until his predicament at the London-based club improved following Tuchel’s appointment.

Elsewhere, Chelsea are allegedly planning to make a £78m offer for Borussia Dortmund forward Erling Braut Haaland this summer.

The 20-year-old ace is enjoying an outstanding season with Dortmund, contributing 23 goals from just 21 games in the Bundesliga and Champions League.

BVB will be powerless to retain the services of the Norway international if any club activates an exit clause which goes live in 2022.

However, according to WinSports, the Blues are determined to win the hunt for the emerging star by signing him at the end of the campaign.

While the alleged sum being considered by Chelsea is above Haaland’s asking price, Die Borussen are expected to wait for higher proposals with Real Madrid and Manchester City also monitoring the current situation.
